My brother I just died in April 2022, he was a chiropractor. He has years worth of x-rays I’m presuming 500 pound anyways, my sister-in-law is giving that to me. Just for this purpose… Thank you so much for the info!
For higher yield buy photographically unprocessed film , Silver halogen that is on the gelatin of the film was already used to create silver oxide ( the dark image on the film) hence creating negative image, Most of silver halogen (silver bromide ) was already regenerated to silver and stripped in fixer bath . Recovered silver remained in the hypo and you bought material that had less than 20 % of original silver content. I checked on Ebay for unprocessed Xray film and for the price you paid you could buy unexposed film and recover 5 times the amount of silver you received, You were correct to assume 2.5 oz of silver from 5,5 lb of film, but because most of the weight was in cellulose and silver had already been extracted before you bought it 1/2 oz is a good yield . I have been working for a large photo company for 20 years and silver recovery was part of my job. Recovery was done by methods other than bleach stripping, and hypo solution would yield 1 oz of purest silver per 1000 sq. ft of combined photographic paper and film processed.
Hello. The conventional film are using developer to develop the image. Now the medical industry mainly use computered radiography which we call it CR film in Malaysia. Is it contain silver too? I have some sample photo of it. Thank you. Khoohmkhoo956@gmail.com Here's my mail. Thank you.
Tip to cut the time removing silver from x-rays. The silver is only on the dull side. Put two sheets together back to back exposing both dull sides while dipping. I've been a photographer for 40 years.
Did a demolition in an old doctor's office and took to the shop over 1k lbs of xrays, a summer project and your video is the best put there. Common chemicals while others weRe asking for money for the chemical list, you shared this with us for free, thank you very much, great video.
Well, it's 3 full pallets, now that I moved them again it's more like 2k pounds. Willing to donate one full pallet to you and the channel, if you do a video showing what a 3 lbs plus of silver looks like, but it would take awhile, but worth it maybe for the channel and the cash. It would be cool to get a high school chemistry class to help you or something. Just thought I would offer, love your channel and I've learned a lot, the offer is there if you decide on it, but I'm in Detroit. Best wishes, and keep rockin.
Dave, thank you for the kind offer. Are you certain that the films are silver? Some processes use film that has no silver. I'll bet that a pallet of film weighs a ton.
I think you did great I will look for a lot of videos and couldn’t find a lot to explain specially when somebody’s talking you through it makes it better it was maybe one or two other videos that was silent great job
Hi. Thanks for the video. I have actually done the silver chloride/lye/ sugar methods a number of times. I like it. The largest batch I did was 40#'s Xrays from which I got about 2 ozt of silver. I used lye to strip the Xrays, It appears your bleach did it much quicker, so I may try that in the future. When it came to the sugar, Kyro syrup alone or with a little honey and water works great. Much quicker. If you put too much sugar in you'll have brown waste which is the sugar being carmalized. It has caused me not problems. If I can find the picture of the bar I got I'll post it. The yield you got appears consistent. I didn't expect you to get the couple ounces you mentioned in the beginning of the video with the amount of Xray film you had. It of course varies with the quality of the Xrays. Older Xrays (which mine were) have a denser coating on them compared to today's, that is if you can find Xray today with all the places going to digital. Thanks again for the video!
This was really good! Now if we can find a supply of free x-rays and photo film I think we would be set don't you?! Thank you for sharing this it was great!
have about 700 lbs of plastic film with silver on it after watching this video i think it will stay where it is seems like to much trouble for what is recovered a great project if you have the time keep up the great videos thanks again
People that have a stack of x-ray films layin' around can do some reclaiming! I really hope there isn't anybody out there that has 5lbs of their own x-ray pics out there! Interesting process! Thanx bud!
interesting as an educational purpose ! it gives sense on the word "recycling", thanks for all your work, i also enjoy all you videos about gold refining
When I use this process for developed black and white film ( which is what X-ray film is) I always use a vacuum filter before converting AgCl to AgO. There is always a gross amount of the emulsion and silverhalide carried over with this process. Your yield was better than expected. Better than the same mass of keyboard mylars.
Hello, i have a question, i started extracting silver from old printing negatives (which is the same as an xray film but used to burn printing plates), i did it following this videos using the exact same materials (bleach, sodium hydroxide,white sugar and hot water), the remaining cement silver that i get is more like a cement colour and a mud texture, i put it in the sun to dry, but it takes too long to dry, can you give me an email to send you a picture so you can take a look a it and see if i did something wrong?
Amazing. I had no idea that was that easy. I worked for a company dealt with recycling xrays, but we shipped them to a refiner. I was doing the math and it was impressive for a 25,000 pound truck load at a time. We did that every couple of months.
The yield was roughly 0.1 troy ounces per pound or 1 troy ounce for every ten pounds. So 25k pounds would produce 2500 troy ounces! It took me six hours to get the silver off of five pounds. 25,000 pounds would take me the rest of my life.
Thank you for your time and efforts. And expence . Your efforts have saved us time effort and money. But most of all...thank you for emphasizing safety.too many videos out there gonna get someone sick or hurt.😎
If I did this again I'd use a 5 gallon bucket instead of the small bucket that I used in the video. If I remember it took me 6 hours to strip five pounds! Good luck with it.
This is a great video..many thanks, having worked in the medical X Ray industry for years, I have a good stock of X Ray film silver halide recovered from electrolysis units, I would say it is around 5kg....however it is like a fine black sand with a sulphur like odour, it is very dense and settles quickly in distilled water, IE it forms a sand like layer, but it is black and not grey like your metallic residue detailed here...do you have any suggestions how to process it to metallic silver ( it is definitely silver as it has come from recovery machines) thanks
In my experience, it may be silver oxide. Silver oxide is black in color, in my experience. If it were me, I would get a small sample, say about 100ml volume, and I'd put it in a crucible and heat it to 1000 degrees C or 1948 degrees F. Silver oxide, when heated, releases the oxygen and leaves behind pure metallic silver metal. Another experiment that I would try is to add a gram of sodium hydroxide to a 100ml sample of the black material, then stir and add some sugar. If it's silver oxide then I would expect to see the black silver oxide turn to pure elemental grey silver powder. This is what I would do, if it were me.
Refining my own bullion and a retired paramedic. I would have never thought about x-ray film. I have no plans to either but it was a great and educational video. Thank you
there is a some x ray film which is exposed by light but differ from used x ray film so this kind of x ray film only washing by naoh and filter then melt plus getting a product i think so because the silver is accumulated mainly.Say something and start this project?
Well in case you will repeat this recycling I suggest 2 faster methods like: - Cut the plastic: A paper shradder would be GREAT cheap and effective. A paper cutter as you used for cutting the electronics fingers from those 150++ boards that you got more gold than you expected - Bath the plastic: I suggest using something short and larger so that you can put the plastic all inside without the need of tipping in-out something like OLD PHOTO DEVELOPING but bigger. From what I can spot in the video, the silver would go away from the plastic very nice using a brush. - Settling of the metals: I think that some kind of "VIBRATION" would make the settling A LOT FASTER! I would be nice to make a desk with a drill that is gently beating the undersurface of the desk, in this way all desk would slightly vibrate to facilitate the settling. Hope that would be a nice addendum to your future X-ray silver recovery method ;)
Great demonstration, I've always wondered how silver recovery from film works. That 0.525oz is a much lower yield than I expected from over 5lbs of material, which is OK, because now I have a realistic idea of what to pay for this type of silver recovery scrap. Thank you so much for taking the time to explore all of these different recovery and refining methods, and sharing your findings with all of us! Do you have a Patreon or some account where I can make a monetary donation to help keep these videos coming?
I learned a lot from this. Mainly, not to buy films from eBay. But I wish I kept the stack of old panoramic dental films I saw a few years ago get tossed. Maybe I can find a free stack again and refine them.
Great video, I'm just wondering if shredding the xrays then dropping in a bucket of bleach and stirring would not maybe save a bit of bleach or cutting into smaller squares so that they can all get dropped into the bucket at once?
I worked in the printing industry (four color pressman) for sixteen years years (1989-2005), and we always operated a darkroom to make film negatives for plate making. A company would come by once a month and collect the discarded film negatives and used developer solutions to recover the silver from. They collected these same materials from printing companies all over the Phoenix metro area, and they got them for free! I imagine that a tidy profit could have been made, since they are getting the silver bearing materials for free. A streamlined operation could be set up, and you could be in the black fairly quickly (I assume). It looks like quite a lot of film negatives and used developer is needed to produce an ounce of pure silver, but once again, if you're getting the materials for free, the bleach, sodium hydroxide, and sugar are very inexpensive. The most significant amount of overhead will be for labor. Unless you are doing this for yourself, you will need to pay someone to work your operation. You'd have to keep them busy, and process enough material to cover your expenses for chemicals and wages. I imagine that they were making money at it, since they were in business for the entire time that I was in the printing industry.
It's high up in the list, I just need to get it started. That's the hard part, getting started. Once that's over it comes fairly quickly. If I didn't have this pesky job I could devote full time to my video production. But it was once told to me that once you turn your hobby into your work, then it becomes just that - work!
When using an x-ray automated x-ray film processor a silver recovery unit is attached in series to and to the fixer tank drain line. The silver recovery may be an electrical type which traps the silver magnetically to the recovery unit or is simply a 5 or 10 gallon bucket with lid stuffed with steel wool which attracts the silver to the steel wool. Each month the processor needs maintenance for cleaning and fresh chemistry to develop the x-rays and when the fixer tank is drained from the automated film processor the fixer flows through the recovery unit before going down the drain. (also all overflow fixer from everyday processor use goes through the silver recovery unit). Depending on your film volume the recovery units are cleaned or taken outright and refined in a similar manner as this video.
The bleach batch you used are of what content each ie each bottle content is how many ml, or I should just get a gallon and empty into the bucket. Secondly the bucket that have water in it, it is just water or a combination of water and something else? Thanks as I await you response.
We used to recover silver from the fixing bath of black and white film development. We used powdered zinc to precipitate the silver out of the solution. Allowing the zinc silver mix to settle out we would recycle the fixing bath and allow the mud to dry. This mud can be smelted to separate the zinc from the silver.
Smelting is a term used to describe extracting metal from ore. To seperate the zinc and silver, both are dissolved in hot dilute nitric acid. Then copper metal is introduced into the acidic zinc/silver solution. Zinc, being above copper in the reactivity series of metals, will stay in solution. Silver being located below copper in the reactivity series of metals, will cement (precipitate) out as nearly pure silver metal as a grey powder that looks like wet cement. This is where the term "cement" comes from. (Edited once for spelling).
Is there any silver left in developed color photos from the late 70's, 80's to 2000 ?(common photos processed from a Wal-mart or equivalent)? Thank you.
Never mind. I should have watched the entire video before I asked the question. Got interrupted early on and just had time to watch the entire thing. Thanks for the video!
So far Im at 20:32. I really like how those x-ray films can be harvested so easily for their silver! ... An idea came to mind that, perhaps, the water and bleach could be distilled such that you have just the bleach separated with more of your silver compound left mostly alone; not sure if that would work, but perhaps if someone had a lot of x-ray film to process it might make the process easier. ... As well as possibly taping the film lengthwise, placing a roller into the bleach and water, and setting a motor to turn the film through the two sections at just enough speed to allow for the silver to be harvested automatically without the need for assembly-lining it... Gosh, am I lazy.
I wonder how much is in your waste buckets , and how much reaction did not finish ? Is there a test for silver in , during these processes - to see if the drop reaction is finished ? Thanks again
Hey sir...did u know by what chemical we can precipitate the photographic chemical waste which have in photo house?...and in ur exp,t is it naoh is enough...using nacl03 is give us best silver?
Hi, I followed the same steps you did there with the same amount of x ray. All I get was 0.2 troy ounce. Can I know which step is crucial getting all the silver out? Maybe I should add hips of sodium hydroxide before adding in table sugar ?
Great video, thanks. Can I add to the calls for a video on the reclamation of silver in suspension please ! Years ago, when film development was manual, we use to sell the spent Fix solution for the modern equivalent of 20 Dollars/Gallon (with a lot of wheeling and dealing between us and the scrapman) I was told by old heads that the process involved a trickle charge of current and produced 'Black Silver' - I've still got some 'Silver Estimating' papers somewhere... i was also told that silver recovery from film was done by burning the excess away to leave silver behind - I've no idea if this was true, its just what I was told !
Fill a bucket full of steel wool and pour the fixer in stirring ever so often and then letting the silver bind to the steel wool....once all the fixer is gone and drained out rinse the steel wool with water and walla....there's your silver. I have over 5,000 pounds of film in my shop so I believe bringing it straight to the refinery works best for me. BTW.....the steel wool has some sort of chemical electrical reaction to the fixer and silver so the silver binds to the steel wool.
Excellent video. I wonder what one would get as yield from soldered copper pipe ends, since that type of solder contains silver. Not to mention solder that is sucked off of old print circuits. I gather quite a bit of it working on electronics, especially vintage electronics where parts are soldered to contact bridges. Thanks for your sharing your knowledge and video. It was entertaining and interesting
I bought some silver solder from the welding supply store. I've had it for about two years now. A whole tube of it for about $50 bucks. I had forgotten all about it. It would make a great video. Thank you.
Thanks for the Video, I have one question , what is the bleach? which chemical is it? please clarify to me and i want to recover silver from X-ray film.
Hi, nice video! Tried this today with little to no effect. X-ray film was shedding slight amounts of a silver but the images did not come off like yours... Any advice?
@@sreetips Hi I followed the video and got my silver today. However I can't wash the impurities on the silver in the last step. They just won't come off in my low heat solution. Could you explain what temperature you used to cook the silver in the solution of distilled water and sulfuric acid? How to let the impurities come off?
Would you do a video of a complete process of recovering silver from the keyboard mylars? I've seen a couple on RUclips but I think your methodological way of doing things will greatly benefit such a video.
hey hey....can we get the silver product by using developer(whis is found in hospitals and body of radiology process).Now i think after i filter the developer chemicals then burn out and get the one i interested.What do u see bro?
Someone made a comment about settling more with regards to your yield. I didn't expect 2 ounces from the amount of Xray film you had there from my experience, but I do think that making sure every bit is converted to silver chloride and letting the silver chloride settle until liquid is clear before decanting would've increased your yeild. Then at that point lye until dark black (from my experience) and no more reaction, then a liquid sugar like Kyro syrup diluted just a little and add until you start to get it very brown (excess sugar is carmelized) then rinse, let settle, and repeat until clear. Then you can be confident you have converted and recovered ALL the silver present. I would've still been surprised if you'd gotten a whole troy ounce but you might have recovered more. Still, I love your videos. Much respect!!
Scott its a film. It will have no silver chloride which is less sensitive and mainly is is used in contact printing, Film will contain Silver bromide or in rare cases silver fluoride , which will be the emulsion.depending on application. Buying exposed/processed film by pound is like buying a goldfish with 5 gallons of water and paying per pound.
John Abramyan Hi John. you missed the word **converted** the silver based emulsion is converted to silver chloride then converted to silver oxide by the lye, then to metallic silver by the sugar.
John Abramyan. It’s called *yield*. If you know how many goldfish each lb of water yields you could purchase goldfish by water weight. Knowing that older heavier coated X-ray film gave me 2 ounces nearly pure silver from approximately 40lbs of film goes toward estimating “how much to pay by weight for that goldfish containing water”. 😉
Don’t know. I only did this once. There were no videos on this. One channel had bits and pieces then referred the viewer to a web site for a fee for the rest of the process.
I do not. I bought this online just to make the video. Some X-ray film contains no silver at all. I bought this because it was certain to have silver. I don’t know how to tell the difference
Would this process work on old negatives too? How about old movie films or slides? I've watched this several times and keep wondering if it would apply.
Really like the video but can you explain what the purpose for the Sodium Hydroxide and table sugar? There are other videos show placing the silver sludge in a coffee filter and going straight for the melt. Much thanks
I was thinking that the sludge was a chloride since it came off with chlorine bleach. I used lye to convert the silver chloride to silver oxide - but I do not know if this was even necessary, it didn’t react like I expected, but this whole thing was a big experiment. After converting silver chloride to silver oxide (I think) then I added sugar to convert the silver oxide to pure silver metal. That seemed to work fine. But I may have had silver oxide before adding the lye - I don’t know. Silver oxide will melt into pure silver metal without the lye and sugar. I only did this once. I’ll probably never do it again. It was messy, time consuming, produced much waste that had to be treated before disposal and the yield was low. I couldn’t find a video on it. The videos that existed back then showed bits and pieces, then directed you to a web site and for a fee you could get the rest of the process. This disturbed me so I decided to do a video of the complete process.
@@sreetips I think you gave all of us what we needed and proved your point. The process was interesting and easy to follow and the result was spot on. Thank you...
Hey sreetips. Me again! so my question now is what I got from bleach and rinse Not grey like you got. Haven’t added lye or sugar. Is that good or is it waste at this point. One of your other videos deals with white silver chloride is that what I may have hear. Any help is good help. And happy holidays been binge watching your channel.
@@chrisgiaquinto5064 Chris, I’m not sure if you resolved your color question but when I stripped with bleach I got a pretty light gray precipitate. After the lye and sugar addition I rinsed it a few times...blacker with each rinse.
in ur particular study have u found or did u know whether the x ray film silver less or not and what type of x ray film having silver? medical or digital?ultrasound or dental?...
Thank you so much For doing that.. Yes you demonstrated how to extract the silver and also gave us kinda a formula to go by when doing ut ourselves and wether or not its worth it to follow the project all the way through or not.... That's assuming that all x-rays are generally about the same in their silver content... I would love to invest to get started... But the way things are going right now.. I am building a gravity fed water filtration system.. So we can have clean water.. Things are so different anymore.. The carefree days have vanished.. These are different times.. I think a good water filtration system will be the smartest thing i have ever done... Even better than college.. Ha ha ha ha ha ha. Well the smartest thing Next to making colloidal silver.. Have a nice evening
No need, I know that there is probably a trace of silver left suspended in the solution. There is also a small amount in the waste I poured off after adding lye and sugar. But the amounts are tiny. I'll check them before I dispose of the waste.
Because lye (sodium hydroxide) will convert any silver chloride that is present to silver oxide. Please remember that I made this up as I went along. I relied heavily on my years of refining experience to make this video.

there is a some x ray film which is exposed by light but differ from
used x ray film so this kind of x ray film only washing by naoh and
filter then melt plus getting a product i think so because the silver is
accumulated mainly.Say something and start this project?
Well in case you will repeat this recycling I suggest 2 faster methods like:
- Cut the plastic:
A paper shradder would be GREAT cheap and effective.
A paper cutter as you used for cutting the electronics fingers from those 150++ boards that you got more gold than you expected
- Bath the plastic:
I suggest using something short and larger so that you can put the plastic all inside without the need of tipping in-out something like OLD PHOTO DEVELOPING but bigger.
From what I can spot in the video, the silver would go away from the plastic very nice using a brush.
- Settling of the metals:
I think that some kind of "VIBRATION" would make the settling A LOT FASTER!
I would be nice to make a desk with a drill that is gently beating the undersurface of the desk, in this way all desk would slightly vibrate to facilitate the settling.
Hope that would be a nice addendum to your future X-ray silver recovery method ;)
I suggest he wet the emulsion and scrape it off with a razor blade . Just kidding
Great demonstration, I've always wondered how silver recovery from film works. That 0.525oz is a much lower yield than I expected from over 5lbs of material, which is OK, because now I have a realistic idea of what to pay for this type of silver recovery scrap.
Thank you so much for taking the time to explore all of these different recovery and refining methods, and sharing your findings with all of us!
Do you have a Patreon or some account where I can make a monetary donation to help keep these videos coming?
Kyle, I'm not sure how that works. I'll have to get one set up. Thank you.
Which salts are added plz tell
I learned a lot from this. Mainly, not to buy films from eBay. But I wish I kept the stack of old panoramic dental films I saw a few years ago get tossed. Maybe I can find a free stack again and refine them.
Great video, I'm just wondering if shredding the xrays then dropping in a bucket of bleach and stirring would not maybe save a bit of bleach or cutting into smaller squares so that they can all get dropped into the bucket at once?
Thankyou I enjoyed watching that unfold
That was very interesting. Thank you.
I worked in the printing industry (four color pressman) for sixteen years years (1989-2005), and we always operated a darkroom to make film negatives for plate making. A company would come by once a month and collect the discarded film negatives and used developer solutions to recover the silver from. They collected these same materials from printing companies all over the Phoenix metro area, and they got them for free! I imagine that a tidy profit could have been made, since they are getting the silver bearing materials for free. A streamlined operation could be set up, and you could be in the black fairly quickly (I assume). It looks like quite a lot of film negatives and used developer is needed to produce an ounce of pure silver, but once again, if you're getting the materials for free, the bleach, sodium hydroxide, and sugar are very inexpensive. The most significant amount of overhead will be for labor. Unless you are doing this for yourself, you will need to pay someone to work your operation. You'd have to keep them busy, and process enough material to cover your expenses for chemicals and wages. I imagine that they were making money at it, since they were in business for the entire time that I was in the printing industry.
Very good friend 👏👏👏👏
Great Video, Great in accomplishing what you set out to do and teach us. For that i am grateful. Is the catalytic converter video in the works?
It's high up in the list, I just need to get it started. That's the hard part, getting started. Once that's over it comes fairly quickly. If I didn't have this pesky job I could devote full time to my video production. But it was once told to me that once you turn your hobby into your work, then it becomes just that - work!
Awesome Vid as usual!
I like this video and teaching method. Thanks.
Thank you for this video.
Great video as always. I'd like to echo the requests for a video on recovery of silver from waste fixer solution.
When using an x-ray automated x-ray film processor a silver recovery unit is attached in series to and to the fixer tank drain line. The silver recovery may be an electrical type which traps the silver magnetically to the recovery unit or is simply a 5 or 10 gallon bucket with lid stuffed with steel wool which attracts the silver to the steel wool. Each month the processor needs maintenance for cleaning and fresh chemistry to develop the x-rays and when the fixer tank is drained from the automated film processor the fixer flows through the recovery unit before going down the drain. (also all overflow fixer from everyday processor use goes through the silver recovery unit). Depending on your film volume the recovery units are cleaned or taken outright and refined in a similar manner as this video.
The bleach batch you used are of what content each ie each bottle content is how many ml, or I should just get a gallon and empty into the bucket.
Secondly the bucket that have water in it, it is just water or a combination of water and something else?
Thanks as I await you response.
I can't remember. I think I added 1/2 gallon of bleach to each bucket.
We used to recover silver from the fixing bath of black and white film development. We used powdered zinc to precipitate the silver out of the solution. Allowing the zinc silver mix to settle out we would recycle the fixing bath and allow the mud to dry. This mud can be smelted to separate the zinc from the silver.
Smelting is a term used to describe extracting metal from ore. To seperate the zinc and silver, both are dissolved in hot dilute nitric acid. Then copper metal is introduced into the acidic zinc/silver solution. Zinc, being above copper in the reactivity series of metals, will stay in solution. Silver being located below copper in the reactivity series of metals, will cement (precipitate) out as nearly pure silver metal as a grey powder that looks like wet cement. This is where the term "cement" comes from. (Edited once for spelling).
Is there any silver left in developed color photos from the late 70's, 80's to 2000 ?(common photos processed from a Wal-mart or equivalent)? Thank you.
I’m not sure. Some films are thermal and have no silver at all
Great video. Thank you very much for your wonderful video.
I have just acquired about 300 pounds of films. Any other vids, yours or otherwise, on converting to silver??
Does the Clorox react with the silver or does it just "wash" the silver off of the film sheet?
Never mind. I should have watched the entire video before I asked the question. Got interrupted early on and just had time to watch the entire thing.
Thanks for the video!
Which Type of bleach is used ?
So far Im at 20:32. I really like how those x-ray films can be harvested so easily for their silver! ... An idea came to mind that, perhaps, the water and bleach could be distilled such that you have just the bleach separated with more of your silver compound left mostly alone; not sure if that would work, but perhaps if someone had a lot of x-ray film to process it might make the process easier. ... As well as possibly taping the film lengthwise, placing a roller into the bleach and water, and setting a motor to turn the film through the two sections at just enough speed to allow for the silver to be harvested automatically without the need for assembly-lining it... Gosh, am I lazy.
can we use the cleaning x ray film again like original x ray film ?
What are the names of the last material to polish the silver
I wonder how much is in your waste buckets , and how much reaction did not finish ?
Is there a test for silver in , during these processes - to see if the drop reaction is finished ?
Thanks again
Hey sir...did u know by what chemical we can precipitate the photographic chemical waste which have in photo house?...and in ur exp,t is it naoh is enough...using nacl03 is give us best silver?
I don’t know
Hi, I followed the same steps you did there with the same amount of x ray. All I get was 0.2 troy ounce. Can I know which step is crucial getting all the silver out? Maybe I should add hips of sodium hydroxide before adding in table sugar ?
I only did this once. Not much experience.
Really informative. Learned something for sure.
Hi Sir, what is the powder u use when heating up the silver cement?
Thanks and HOPE YOU CAN REPLY ME
Borax
Great video, thanks. Can I add to the calls for a video on the reclamation of silver in suspension please !
Years ago, when film development was manual, we use to sell the spent Fix solution for the modern equivalent of 20 Dollars/Gallon (with a lot of wheeling and dealing between us and the scrapman)
I was told by old heads that the process involved a trickle charge of current and produced 'Black Silver' - I've still got some 'Silver Estimating' papers somewhere...
i was also told that silver recovery from film was done by burning the excess away to leave silver behind - I've no idea if this was true, its just what I was told !
Fill a bucket full of steel wool and pour the fixer in stirring ever so often and then letting the silver bind to the steel wool....once all the fixer is gone and drained out rinse the steel wool with water and walla....there's your silver. I have over 5,000 pounds of film in my shop so I believe bringing it straight to the refinery works best for me.
BTW.....the steel wool has some sort of chemical electrical reaction to the fixer and silver so the silver binds to the steel wool.
Excellent video. I wonder what one would get as yield from soldered copper pipe ends, since that type of solder contains silver. Not to mention solder that is sucked off of old print circuits. I gather quite a bit of it working on electronics, especially vintage electronics where parts are soldered to contact bridges.
Thanks for your sharing your knowledge and video.
It was entertaining and interesting
I bought some silver solder from the welding supply store. I've had it for about two years now. A whole tube of it for about $50 bucks. I had forgotten all about it. It would make a great video. Thank you.
Thanks for the Video,
I have one question , what is the bleach? which chemical is it? please clarify to me and i want to recover silver from X-ray film.
Sodium hypochlorite 6% solution. It's called chlorox in the U.S. It can be bought at the grocery store. Used to whiten cloths in the laundry.

Excelente proceso.
What if i use this to silver plate
i have one idea that is after we clean the x ray film can we reuse the x ray film
I wonder if this would work with silver mylars out of the keyboards
Some one has posted a comment stating that it would work on myylars.
Hi, nice video! Tried this today with little to no effect. X-ray film was shedding slight amounts of a silver but the images did not come off like yours... Any advice?
I’ve only done this once. Not all X-ray film contains silver. I don’t know how to tell.
Good time and health! How many x-rays were there in the beginning by mass? or by area m2?
5 pounds
This video is fantastic! May I ask you what is the white powder that you added in the very last after you roast the silver using torch lighter?
That was some borax
@@sreetips Thank you!
@@sreetips Hi I followed the video and got my silver today. However I can't wash the impurities on the silver in the last step. They just won't come off in my low heat solution. Could you explain what temperature you used to cook the silver in the solution of distilled water and sulfuric acid? How to let the impurities come off?
whether bleach liquid for clothing can be used
and what is the second chemical component used
I used bleach for cloths. Then I see lye to turn the chloride to silver oxide. Then I used sugar to convert the silver oxide to pure silver metal.
Is borax needed during the combustion process?
Would you do a video of a complete process of recovering silver from the keyboard mylars? I've seen a couple on RUclips but I think your methodological way of doing things will greatly benefit such a video.
It's probably the same process with even less silver to get.
Oh, O.K.
hey hey....can we get the silver product by using developer(whis is found in hospitals and body of radiology process).Now i think after i filter the developer chemicals then burn out and get the one i interested.What do u see bro?
I don’t have any experience with that
Someone made a comment about settling more with regards to your yield. I didn't expect 2 ounces from the amount of Xray film you had there from my experience, but I do think that making sure every bit is converted to silver chloride and letting the silver chloride settle until liquid is clear before decanting would've increased your yeild. Then at that point lye until dark black (from my experience) and no more reaction, then a liquid sugar like Kyro syrup diluted just a little and add until you start to get it very brown (excess sugar is carmelized) then rinse, let settle, and repeat until clear. Then you can be confident you have converted and recovered ALL the silver present. I would've still been surprised if you'd gotten a whole troy ounce but you might have recovered more. Still, I love your videos. Much respect!!
Scott its a film. It will have no silver chloride which is less sensitive and mainly is is used in contact printing, Film will contain Silver bromide or in rare cases silver fluoride , which will be the emulsion.depending on application.
Buying exposed/processed film by pound is like buying a goldfish with 5 gallons of water and paying per pound.
John Abramyan
Hi John. you missed the word **converted** the silver based emulsion is converted to silver chloride then converted to silver oxide by the lye, then to metallic silver by the sugar.
John Abramyan.
It’s called *yield*. If you know how many goldfish each lb of water yields you could purchase goldfish by water weight. Knowing that older heavier coated X-ray film gave me 2 ounces nearly pure silver from approximately 40lbs of film goes toward estimating “how much to pay by weight for that goldfish containing water”. 😉
That was certainly a labor of love 😍
So found your channel a week or so ago and I got hooked. How much higher would the yield be with "green" or undeveloped film?
Don’t know. I only did this once. There were no videos on this. One channel had bits and pieces then referred the viewer to a web site for a fee for the rest of the process.
@@sreetips I can send you 8.5 lbs of un-exposed film if you want to run the comparison.
The film your using is considered wet do you have a procedure for dry view? I
I do not. I bought this online just to make the video. Some X-ray film contains no silver at all. I bought this because it was certain to have silver. I don’t know how to tell the difference
So which chemical in the bleach does the stripping as bleach is usually a combination of chemicals?
Sodium hypochlorite 6% solution
Would this process work on old negatives too? How about old movie films or slides? I've watched this several times and keep wondering if it would apply.
Possibly. Put a piece in some bleach water and see what happens
Really like the video but can you explain what the purpose for the Sodium Hydroxide and table sugar? There are other videos show placing the silver sludge in a coffee filter and going straight for the melt. Much thanks
I was thinking that the sludge was a chloride since it came off with chlorine bleach. I used lye to convert the silver chloride to silver oxide - but I do not know if this was even necessary, it didn’t react like I expected, but this whole thing was a big experiment. After converting silver chloride to silver oxide (I think) then I added sugar to convert the silver oxide to pure silver metal. That seemed to work fine. But I may have had silver oxide before adding the lye - I don’t know. Silver oxide will melt into pure silver metal without the lye and sugar. I only did this once. I’ll probably never do it again. It was messy, time consuming, produced much waste that had to be treated before disposal and the yield was low. I couldn’t find a video on it. The videos that existed back then showed bits and pieces, then directed you to a web site and for a fee you could get the rest of the process. This disturbed me so I decided to do a video of the complete process.
@@sreetips I think you gave all of us what we needed and proved your point. The process was interesting and easy to follow and the result was spot on. Thank you...
Will the bleach work with the silver on keyboard mylars?
I don't know, I've never tried keyboard mylars.
Thats the best way ĺ have seen on youtube
Hey sreetips. Me again! so my question now is what I got from bleach and rinse Not grey like you got. Haven’t added lye or sugar. Is that good or is it waste at this point. One of your other videos deals with white silver chloride is that what I may have hear. Any help is good help. And happy holidays been binge watching your channel.
I only did this one time. I'm not sure what you have there. I relied heavily on my years of experience to pull this off.
Hahah I hear that. Wish I could upload a pic thanks anyways
@@chrisgiaquinto5064 Chris, I’m not sure if you resolved your color question but when I stripped with bleach I got a pretty light gray precipitate. After the lye and sugar addition I rinsed it a few times...blacker with each rinse.
Would it be possible to get the full chemical formulae breakdown for the process, each reagent step at a time?
I put it all in the video. It’s all there.
HAVE I TO USE PURIFIED WATER OR DISTILLED WATER WHEN WORKING THE SILVER RECOVERY?
Not in the bleach you dont
in ur particular study have u found or did u know whether the x ray film silver less or not and what type of x ray film having silver? medical or digital?ultrasound or dental?...
I only know that not all X-ray film has silver. I don't know how to tell
Thank you so much For doing that..
Yes you demonstrated how to extract the silver and also gave us kinda a formula to go by when doing ut ourselves and wether or not its worth it to follow the project all the way through or not....
That's assuming that all x-rays are generally about the same in their silver content...
I would love to invest to get started...
But the way things are going right now..
I am building a gravity fed water filtration system..
So we can have clean water..
Things are so different anymore..
The carefree days have vanished..
These are different times..
I think a good water filtration system will be the smartest thing i have ever done...
Even better than college..
Ha ha ha ha ha ha.
Well the smartest thing
Next to making colloidal silver..
Have a nice evening
Sreetips, can't you use your silver id chemical to see if there are any trace of silver in that wash off solution?
No need, I know that there is probably a trace of silver left suspended in the solution. There is also a small amount in the waste I poured off after adding lye and sugar. But the amounts are tiny. I'll check them before I dispose of the waste.
There is a kind of x ray film not refine with bleach I don't know way could you tell me the reason... Thanks
I've only done this one time. And I bought the film because I could use bleach to do it. That's all the experience that I have to share.
Hooo... excellent your vídeo My friend... congratulations for You Chanel...bro... excellent.....
Thank you Mr,but did u use lye?
Because lye (sodium hydroxide) will convert any silver chloride that is present to silver oxide. Please remember that I made this up as I went along. I relied heavily on my years of refining experience to make this video.
What would happen if I added silver chloride to a batch or silver nitrate?
You’d have a mixture. Silver chloride is not soluble in silver nitrate.
May bleach strips silver off from brass, cooper, aluminium base metal ?
I don’t know I’ve never tried it. Chlorine bleach will react with silver and form a passive layer of silver chloride
