My husband and I really would have loved to have seen you turn that into a silver bar or whatever you made from that. Great video! Your voice was calm and informative. Thank you . Hope to see more of your work, but with a melted finished piece.
Check out sreetips channel: ruclips.net/user/sreetips He refines precious metals as well. He made an electrolytic silver cell out of a stainless steel bowl that grows _extremely_ pure silver crystals. He also does a lot of gold refining which is just as fascinating as the silver. It's a great channel if your in to this kind of thing. He also won't make you wait 3 years for the second part of the video.
Nice.. I worked in a metal company way back 2007, we refined Ag. I was assigned in electrolysing Ag .then in melting... As far as I can remembered we used salt and sugar...every time I tell my story to my Friend's they laughs...
using salt and sugar is the way you create elemental silver. salt (sodium chloride) to precipitate silver chloride. Lye (sodium hydroxide) to create silver oxide, and sugar or corn syrup to convert silver oxide to elemental silver. .999 purity
GOLD AND SILVER ARE SAFE INVESTMENT THAN CRYPTO OR OTHER COUNTRIES CURRENCYS..METALS ARE ESSENTIAL THAN CRYPTO....metals are essential than paper currencys///war in the world never stops it is a continuous process till human race finish...
If chemistry had been presented like this when I was at school ,there would be a lot more scientists in the world today 😊. Thank you , who thought chemistry could be so captivating . 😊
Pyrex is a brand name. I am using scientific glass from China 😀 It's the same glass, I'm sure Pyrex has a better quality control. But as a rule of thumb you want to use scientific glass in the lab.
How much actual silver did you end up with after the melt? Did you refine it again after melt to get closer to the 99.999? You left a lot of questions open great video but a lot of questions.
That's a good question 😂 I actually just added that silver powder to a batch of silver powder from another batch. Then I melted it into silver shot. Then I put it through my electrolytic silver cell. Then I usually end up pouring 100 troy ounce bars from the silver crystal.
I'm a silver nut just like everyone else watching this video, but I bet he could have sold some of those pieces for more money than their scrap silver value. I realize that some of the pieces were just scrap, but others were sellable to antique collectors, just saying.
You are correct some of the pieces that I have recycled are probably worth more sold as is. I have noticed that unless you're antique sterling silver is perfect (dent and scratch free) you won't get much more than the scrap value. You will also have to wait for someone to come around that is looking for the piece you are selling. I purchase all of my sterling silver as scrap at a discounted price. So I generally end up dissolving everything that my wife doesn't want.
Would it work just as well to melt down the sterling silver first into a bar and then go through the chem refining to melt it back down or would a big chunk be immediately too reactive?
Is there a good place to buy a set up of beakers and pumps/vacuums and other items needed for this process as well as the gold refining process in your other video? Ps: you do excellent videos. Your teaching style is concise and to the point, making it very easy to take notes and follow along. Thanks for making this content! This is the knowledge the big boys don’t want us regular folk to obtain.
Yes eBay. Just search gold fingers to find the scrap.lab glass kits for the other stuff. You can even get whatever chemicals you might need. Happy you enjoyed the video 🤗 😀
Hi Philip, I have a question! as soon as I disolved the plated silver and I filtered the very dark green solution left, in order to neutralise the acidity of it I aded some normal bicorbonate and the liquid turned in a light blue solution!! I added the copper coil but nothing hapened apart of turning the solution in a green liquid again.... big disaster!!! how can I get my silver back??? thank you for the video
If you dissolve silver plate using this method. There will be very little silver in solution it will mostly be base metals. Try again using solid Sterling silver.
How do you get silver off of your hands? I guess picking up the coffee filter left stain on my fingers. Any gloves that are ok to use? I heard not to use nitrile? Does steel added to your copper solution in the end precip your copper or which metal? Great video, thanks! I have lots of silver powder to melt :)
Try using ammonia to remove the silver nitrate stains from your hand. You can use a piece of iron to drop your copper out of solution. I am happy you enjoyed the video 🤗
enjoyed the video, but like most other videos on dissolving 925/sterling jewelry, etc....no one gives a timeline...i.e...how long for the scraps to completely dissolve? how long does it take to precipitate the solution with copper?....just curious...hours, days, ???
It took about six hours to dissolve the silver then I let it cool overnight. it took about six hours to fully precipitate the silver but I let it soak overnight to be sure all the silver had dropped.
Hey Philip. I watched your video a few times and gave this a shot with my son. Everything has worked as you showed so far, except I have some sort of clearish crystal flake after dissolving all of the silver. It is soluble in water, so I don't believe it's silver chloride (I used distilled for everything). Any thoughts?
Hello impressive video lots of knowledge. I am First timer and made a mess of mine, used 65% nitric acid, over shot the solution without knowing and added Cooper pipe into it, pipe has disolved partially. Now question is there a way of separating silver from copper which desolved in solution? Thanks in advance
Just keep adding copper. Eventually you will consume all of your nitric acid. It takes four times as much nitric acid to dissolve copper as it does silver. Once all the nitric acid has been consumed the copper will start displacing the silver. Once all the silver has fallen out of solution you should be able to rinse the copper away with tap water. Any remaining copper or pmg's will be removed upon further purification in a silver electrolytic cell.
Yes, it would appear as though the wildlife has suffered around my residence. But, I am not convinced that I am to blame for the mass deaths. Some of the squirrels have gone hair and toothless. They just sit there and look at you. I'm not an evolutionary biologist but this could actually be a good thing. None of the other surviving animals are eating them. I think the squirrels problem is poor genetics and bad sunlight🤢 That is what probably caused the mutations and deaths. It has nothing to do with the constant toxic fumes being expelled from my lab🤨🤔Thanks, I am happy you enjoyed the video 🤗😀
Very informative but I couldn't get past the gloveless hands. Especially handling the condensed Nitric acid. 1. Ventilation 2. Eye protection 3. Gloves 4. Apron
The copper is extracted when I neutralize my silver waste solutions. I usually don't keep the extracted copper. Because it needs to be melted down and I don't want to contaminate any of my crucibles or furnace.
extracting the copper is relatively easy, buy a bunch of SS dinerware (preferably butter knives) from the local second hand or thrift shop and purt the in the copper nitrate solution. the copper will cement on to them. you can also use regular steel in you effluent catch bucket and it will create a ferrous nitrate solution and drive all copper, and pgm's out of solution if there are any
It starts to crash out immediately. Depending on how much silver is dissolved in the solution. It could take between 4 and 12 hours. There are other factors in play. If the copper gets completely coated with silver crystal it will stop crashing out. So you need to periodically refresh your copper. Once you no longer see crystal's forming on the copper. The silver is out of solution.
Hello. How much amount of nitric acid is needed for 1 kg for silver jewellery (70% purity) and how much amount of distilled water is needed before adding copper plates?
The foils and other remnant metals from the nitric dissolve are easily recovered from a quick round of Aqua Regia... The shortcoming is of course, the time and energy for such small amounts of precious metals, probably as you surmised PGMs.
I usually dissolve sterling silver in 1000 g batches. It usually takes about 1 l of nitric acid to dissolve the 1,000 g. So during the process sometimes the mixture will get a little acidic 😌 but in the end it is all reduced to a nearly neutral state. I always overshoot the silver as the extraction is wrapping up.
@@philipbender956 I wonder what the manufacturers of PMC ( Precious Metal Clay) use. Something that bakes away clean without residue allowing the metals to fuse. Don't think that's epoxy, but what do I know?
One that I built. It is in the corner of my underground bunker / lab. There are many rooms down here. The lab was part of stage 3 of the build. The 1st part of the build contains a Winnebago that I buried at the beginning of the project. That is where I sleep and produce my RUclips videos. Stage 2 is a bunch of old shipping containers that I buried in the same path for food storage. I should probably start work on stage 4 soon. A proper shower and laundry room. At the moment I only clean up with single use alcohol swabs. Then I wear my clothes for 3 days before donating them to good will and buying new ones. In the end I predict it will be cheaper just to build the rooms.
I enjoyed the video, but I have to say, the viewer wants to see the silver melted and poured. Far too many leave out the final melt and pour which really is the best part? It’s the reward for all your work.
How did people figure this out? One day someone says ...hmmm, if I add this to this, it will melt, blow up etc ... lol. Woman brain here, I would never think of something like this out in the wild lol. I feel a strong desire to go shopping for pretty silver things to wear ... 🤪. Cool video though. ☺️
@@danvandertorre6349 The voltage does not affect purity. Voltage will only affect the size and speed of crystal growth. What will affect purity is the concentration of copper in your electrolyte. Or if you produced your electrolyte with an impure source of silver. (Silver contaminated with PGM) I recommend purchasing minted silver to make your electrolyte. I started my cell with a 10 oz bar I purchased off of eBay.
No, just a video on how to make concentrated nitric acid. if you want to purify your nitric acid you need to re distill it and bubble oxygen through it.
Unfortunately copper nitrate isn't very useful in the home. It's mostly used in commercial applications as a dye or antifungal agent. I generally add sodium hydroxide to my copper nitrate Solutions to form copper hydroxide. I then filter off the copper hydroxide then I melt it into copper.
Thank you. The silver I obtained from this method is around %99.900. ln part 2 of this video I will be showing the difference in brightness between this silver and the factory minted silver. As I melt all the silver cement down into silver shot. In part 3 of this video I will be constructing a silver cell in order to produce %99.999 silver Crystal.
He dissolved Sterling silver articles which are .925 or better silver . The gold came in trace amounts from the original sterling that was made. A trace by-product of the mining process of the silver.
Will this method remove iron impurities from the silver? I have a large amount of sterling filings and sawdust. It contains bits of steel from the saw and files. I’ve removed much of it using a strong magnet but enough remains to contaminate any ingots that I make from melting it. Thank you in advance. Your video is very well down.
Unfortunately he forgot you do not get 99.999% pure silver for first run nitric acid and sterling it takes at least 4 runs first run is only maybe 96 to 97 % using 4.6 volt refining several times using a stainless steel container
I have a small suitcase full of sterling silver knives, forks and spoons dating way from my grandmother. I wish I could find someone who would melt it down into nuggets!
I use a slow filter paper. I use distilled water because it does not contain any chlorine. Chlorine will react with the silver nitrate to form silver chloride. a white chalk like substance that will clog your filter paper.
Do you ever add peroxide to the solution. I have been getting better results by replacing 25% of my distilled water with 3%peroxide. 9 out of 10 times great results however i do on rare occasions get a foam on top and a weak reaction. Any ideas what would cause this
No I have not added h202 to my nitric acid silver refining solution. Adding h202 to your distilled water while it is still cold at the beginning of the operation will help convert some of the nitrogen dioxide fumes back into nitric acid.but once the solution is hot any further additions of h202 will only cause it to boil off. Adding h202 to your nitric acid solution will also increase the oxitive power of the nitric acid. Thus causing small silver particulate to dissolve faster resulting in a foam up. (Adding room temperature distilled water will stop your solution from foaming over.) Also if you are getting foam in your solution that doesn't readily dissipate that maybe sign that you didn't incinerate you're beginning silver well enough and there may be some waxy residues.
I have a piece that says Sterling weighted on the bottom of it. It is a candle holder if it's solid silver I should be able to melt it down in a crucible right. I don't think it is plated
I have not had a chance to play with any x-ray developing solution🙁 Sounds like it would make an interesting video. I have seen x-rays recycled but that was after they were already developed and most of the silver had been washed away. I bet the developing solution contains quite a large amount.
@@philipbender956 Thanks for your reply. It definitely does contain a bunch of it. I'd love to see how you made your fume hood! :) not many people using wet developing now, most gone digital. Snap it up while you can! I'm in NZ, so prob not ideal for you! x

Wow, I had no idea. Now how does the powder turn into solid stuff? No wonder I failed chemistry.
It needs to be melted down. The powder is metal it's just finely divided.

Hi sir, will normal water not work in silver refining process copper?
Nirmal water? Do you mean tap water? Chlorine in the tap water will make silver chloride and is a pain to deal with when melting.
Chemistry is awesome.
Hello. How much amount of nitric acid is needed for 1 kg for silver jewellery (70% purity) and how much amount of distilled water is needed before adding copper plates?
What happens if you just melt sterling silver with acetylene torch
You get melted Sterling silver. And a bunch of oxides.
The foils and other remnant metals from the nitric dissolve are easily recovered from a quick round of Aqua Regia...
The shortcoming is of course, the time and energy for such small amounts of precious metals, probably as you surmised PGMs.
All the scraps were thrown in to a bin to be refined later.
Dear Philip, how do you realise at 13:58 that you overshot the nitric acid ?
I usually dissolve sterling silver in 1000 g batches. It usually takes about 1 l of nitric acid to dissolve the 1,000 g. So during the process sometimes the mixture will get a little acidic 😌 but in the end it is all reduced to a nearly neutral state. I always overshoot the silver as the extraction is wrapping up.

If the thinner material devolves quickest, wouldnt it make more sense to start with the thicker material? 🤔
As its eaten add the thinner stuff.
Tin doesn't dissolve easily in nitric, seems more plausible than gold, paladium or platinum on sterling silver.
I was thinking it just didn't dissolve because he had more silver than acid...which was his stated intention.
Where is part 2 video?
Very cool, I was hoping for a part 2 where you melt it down into a bar, or bars, or rounds.

What was it before you smelted it?
I was wondering so this gives you 999 silver, do you use electric power to crystallise it next to get the 5 9s.

He dissolved Sterling silver articles which are .925 or better silver . The gold came in trace amounts from the original sterling that was made. A trace by-product of the mining process of the silver.
Will this method remove iron impurities from the silver? I have a large amount of sterling filings and sawdust. It contains bits of steel from the saw and files. I’ve removed much of it using a strong magnet but enough remains to contaminate any ingots that I make from melting it. Thank you in advance. Your video is very well down.
Yes. It will just take more nitric acid to dissolve the ferrous metals.
Unfortunately he forgot you do not get 99.999% pure silver for first run nitric acid and sterling it takes at least 4 runs first run is only maybe 96 to 97 % using 4.6 volt refining several times using a stainless steel container
I have a small suitcase full of sterling silver knives, forks and spoons dating way from my grandmother. I wish I could find someone who would melt it down into nuggets!
If you want to sale them, let me know
It sounds like it may be more valuable as the silverware. Try selling it on eBay. You should get more than scrap value.
What do you need to do to Get out The gold? Thanks!
Filtration
Grate video. Which grade filter paper use?. Why use distril water, why not normal water.
I use a slow filter paper. I use distilled water because it does not contain any chlorine. Chlorine will react with the silver nitrate to form silver chloride. a white chalk like substance that will clog your filter paper.
Thanks.
How long time coper drop in nitric solutions?
@@jhumpapanday496 usually a couple of hours. But leave the copper in for 24 hours to be sure all the silver has dropped.
@@philipbender956 thank you sir
Do you ever add peroxide to the solution. I have been getting better results by replacing 25% of my distilled water with 3%peroxide. 9 out of 10 times great results however i do on rare occasions get a foam on top and a weak reaction. Any ideas what would cause this
No I have not added h202 to my nitric acid silver refining solution. Adding h202 to your distilled water while it is still cold at the beginning of the operation will help convert some of the nitrogen dioxide fumes back into nitric acid.but once the solution is hot any further additions of h202 will only cause it to boil off. Adding h202 to your nitric acid solution will also increase the oxitive power of the nitric acid. Thus causing small silver particulate to dissolve faster resulting in a foam up. (Adding room temperature distilled water will stop your solution from foaming over.) Also if you are getting foam in your solution that doesn't readily dissipate that maybe sign that you didn't incinerate you're beginning silver well enough and there may be some waxy residues.
I have a piece that says Sterling weighted on the bottom of it. It is a candle holder if it's solid silver I should be able to melt it down in a crucible right. I don't think it is plated
Sterling is .925 silver, not solid silver. It will melt in a crucible.
@@chingching664 okay thank you for your response. Im learning as much about this subject as I can for safety and basic knowledge.
I don't think there is anything safe about it. Cancer causing toxic fumes. You Must be outside upwind or have professional closed exhaust system.
@@chingching664 okay my friend our work shop is well ventilated. I also have a good mask for fumes
@@jayrock1470 Sorry, and good to hear! I don't think you made that clear in the beginning. I like watching your work.
How pure is the silver after this step ?
%98 to %99 The last electrolysis step will remove any platinum type metals that are contaminating the silver.
How much is the cost of this process? Approximately.
As I made the nitric acid the cost of the chemicals was about $20.
Yeah what's up with part: 2. I wanna see it melted to a bar. Awesome video tho
Hello. What is the material of the tube you used to siphon the solution into the funnel?
It was silicone tubing.
@@philipbender956 Thank you for your response. I was afraid the tubing would decompose after a few uses. Do you experience this?
@@tacticalmistress tubing is cheap.
@@philipbender956 Haha I'll take that as a yes. Thank you.
Tool list please?
WHAT IS THE STRENGTH OF NITRIC ACID SOLUTION ❓❓
Hey @philip, I have a bunch of silver in solution from x ray developing. Have you played with this? Thank you! Xx
I have not had a chance to play with any x-ray developing solution🙁 Sounds like it would make an interesting video. I have seen x-rays recycled but that was after they were already developed and most of the silver had been washed away. I bet the developing solution contains quite a large amount.
@@philipbender956 Thanks for your reply. It definitely does contain a bunch of it. I'd love to see how you made your fume hood! :) not many people using wet developing now, most gone digital. Snap it up while you can! I'm in NZ, so prob not ideal for you! x
@@lizzitremayneauthorandequi6127 yes New Zealand is pretty far. I will keep my eye out for it. I am curious as to how much it would contain.
@@philipbender956 I've created a monster! xx
