Sreetips, love your work. Thank you for being a teacher. I was wondering if you would consider making a new/updated Flowchart video? You've updated and altered some of your processes since your last one. Thank you.
I 2nd this. I've almost have all the equipment organized, some back ordered. Material seems to be the biggest issue, everyone thinks even the plated stuff is highly valuable. I know you have the Mrs that does a great job of shopping, do you find online auctions to be good places for material as well?
This was a neat video. Seeing the silver nitrate crystals was fascinating. Thanks for doing a gold plated refine. I know there’s plenty of ppl out there with a lot of gold plated silver wondering what’s the most affective Refining method
I had bought a batch of silver online and it had a bunch of necklaces that were stamp 925 but were obviously gold plated. I was pleasantly surprised as to how much gold each of those necklaces had and surprised that the seller hadn’t pulled those out of the batch but instead included them for the same price as all the other silver. If I remember correctly it was necklaces from Italy, I think it had Milan stamped on it as well. I wouldn’t mind getting my hands on more of that “silver” anytime.
The visual display of reactions underway and certain steps of the process (ie. the rendition of Sreetipsmans Fortress of Solitude [Mrs Sreetips being the one and only green crystal responsible for the construction] in this episode) are simply stunning. They are, surely, one of the most interesting displays of chemistry occurring in this galaxy by a sentient being, second only to, for instance, what is being done with the Large Hadron Collider. Disclaimer (and possibly opening the biggest cans of worms ever): it would be nice to know what the UAP are, so my remarks refer to non-inter dimensional traveling sentient beings. A montage of highlights from your past videos, I believe, may be in order. I do have a reasonably intelligent question about testing whether or not gold is in solution and how the stannous test determines the fact but I will search for the answer before blurting it out. Thank you Sir! for another ausome production.
Love when the Gold in solution finally gets to that bright orange / yellow stage. You just know there's some really good stuff just around the corner. 👍👍
The silver nitrate crystals are purer than the remaining silver nitrate solution, there is even a purification method by recrystallization. I wonder if it were possible to somehow not dissolve these crystals or at least not mix them after dissolving with the rest of the solution to benefit from this side purification.
have you ever thought about getting a handheld XRF gun? I know they are expensive but to be able to see the purity after these refinfings would be very interesting.
I checked into it. They are about as much as a car. But you can rent them: $1500 per week, $4500 per month - includes a visit from local authorities to ensure you are going to use it properly.
Looks like a lot of work cleaning, sorting, etc. Through the years though I have found that thorough prep usually ends up with a better finished product. Appreciate the time and effort you put in with these fascinating vids.
It would be nice to have a NO2 capturing setup to use for regenerating Nitric acid. It would reduce your nitric acid consumption significantly. I visualize some sort of wash tower - where the NO2 is exposed to distilled water and oxygen (atmospheric air should work) and then fed into a condensation column to make sure all the acid condenses.
Thinking on it processing gold plated material would probably be as much for the silver as the gold right? I often pull out my silver crystal and I'm still amazed at how awesome it is! 👍
Fantastic work. I loved Science at School and This Man Wuld have brought Science To Life at School. Keep up the great work Sir. Your Vidios make me smile inside and out .All Thery Best wishes Phil 🇬🇧
Dear Sreetips Just as a suggestion You could melt down the part in first place and afterwards continue with the nitric boils. This way nitric should have a better chance to attack impurities in gold. Just something that I learned from you
Yes, there are at least two alternative attacks. The melting down and digesting in nitric acid is one. Another would be to cast the material up as an anode bar and refine the silver in a silver cell. The remaining slimes containing the gold would then need separate treatment to separate the gold.
Great videos, very informative. Makes a guy wonder how this process could be done in any kind of lucrative way. The amount of time/energy/chemicals spent for 2g was pretty eye opening
You can moisten the paper filter with spritzer and it expands a tiny bit. Then do your fold and sequre with a rubber band to let dry and it will be solid like a drum head. .. but thats probably excessive
That was an expression, there’s not really a ton (2000 pounds) of silver in there. But there is probably about 600 grams of pure silver in that solution.
Dear Sreetips, What brand of ceramic bowls do you use? I used a glass pyrex dish and it exploded into a 100 pieces of glass. Then I used a ceramic dish and it popped and cracked into 10 pieces. Also what temperature do you use?
I know that a volume of solution with gold dissolved in it weighs more than the same volume of plain water. Does it equal the exact amount of gold that it contains? I don’t know, but it probably does.
I think he did it for the RUclips content. He said he would usually use that stuff for inquarting karat gold. Nitric is expensive to buy and I'm not sure that small yield would normally justify the cost in chemicals. Be grateful, he did it for us!
A 2.5 liter bottle of nitric was $50 - so I used 0.8 liters so about 0.32 of a bottle times $50 equals $16 worth of nitric. All other inputs, less than fifty bucks. So $60 to $70 all in. But I’ve already built economies of scale with my setup, so that don’t include that. But I’m really just doing it to create content for my channel.
I was looking for a video that showed me how to get the vermeil off of a silver chain so that it will look nice again. I wound up watching the whole thing. This process seems like it would cost a lot of money to start up and a lot of time to do. I would like to watch the video where you get the silver back ❤🕊️
Sr. Chief, can this process be used for ANY gold plated material? obviously the nitric bath will dissolve out all of the base metals but if one were not planning to harvest the silver, would this process be applicable?
Where do you clean you equipment? There must be residues in the beakers and such, do you have to do something extra to do this? How much silver er did you recover from this? Do you bother the recover the copper now?
Waste treatment. I recover all the silver. I recently purchased $500 worth of copper that should last me several years. Copper is very useful. But once it’s used in the recovery of precious metals, it then becomes waste and not worth trying to recover.
@@sreetips I didn't know that. I saw how copper nitrate was recovered along with dilute nitric acid. Then copper was recover, I just thought if there was a way to remediate a waste stream, it would be worth doing.
That makes good video content, but for me it’s just not worth the time and effort. The last little 2.9g bead of gold that I recovered will probably go for $300 - that’s about 70 pounds of copper. When working with metals that go for tens of thousands per pound, one can’t justify wasting time on 4 dollar a pound metal. Sounds harsh, but I’m so backed up with my precious metals refining that taking time to recover copper (that’s plentiful and cheap) just don’t make no sense.
Am I right in guessing that trying to recover gold plating from stainless steel is a waste of time? Probably too much work for a tiny yield. Whats your thoughts Sreetips?
hi sreetips , hopeful you are well buddy.... I just had a fleeting thought and wondered about your opinion on the subject. Since watching you building your fume hood and following you for sometime now , the walls inside the fume hood have began to amass purple stains , obviously from stains and over spill run away reactions you have had..... i remember the video on the material collecting in your fan and replacing etc etc, would the stains i have mentioned be worth cleaning up and put into paper storage , i mean surely it couldn't hurt and i guess i'm just a bit of a stickler for a clean workspace in any respect. It just seems maybe if this was the case it would be worth doing ??????? Also I have been searching high and low for a copy of the book you reference ( Hoke's ) which seems impossible to buy anywhere , can you help at all >? All the best , Adrian
You know it's funny as many times as you've explained the filter technique, I just now realized that I've been trying to explain it to people for years in another scenario and for another reason. In this scenario it's actually to make it easier to remove said filtered material and make cleaning a filter/pump apparatus of said filtered material much easier. That's a fancy way of saying a fryer filter machine that gets abused by fryers that do a ton of hand breaded/battered frying 😂.
Hey Sreetips, I'm curious. You add H2SO4 to your solution before dissolving you the metals with Aqua Regia. Wouldn't it be better to add it once you've dissolved all of the metals, so that everything is in solution (including any lead), then add the H2SO4 which will drop the lead. I think that adding it before complete digestion could leave some lead in the undissolved material.
G'day just curious obviously I'd still double check like you have to confirm silver behind the gold plate. Is there a standard jewellery mark for silver plated with gold. As always best of luck to you and your family.
I use borosilicate (Pyrex) glass only. Brand doesn’t matter so long as the glass is boro. The casserole dishes bought from yard sales. Provide a catch basin for spills and a sturdy surface for glassware.
Wouldn't bleach also be a test for silver? Looks like your silver test solution is already a reddish color to start with and on the towel its still a reddish color. How do you tell the difference?
you have inspired me and my wife to do this.. we already love going thrifting for things to resell on our eBay store. is there a place you would recommend I could look at to get some of the equipment you're using? used would be preferred
Loved this. Silver nitrate crystals were beautiful. By the way it will always be BUCK-NER funnel for me since that’s how I’ve always heard you say It 🤣
Hello Mr sreetips. Is it better to melt my silver, then keep is as it is? I have never melt before, but i have deside to try and melt some silverbar😊. I need a melht dish, and borax. First glace the dish with borax... And start melth, and put some borax when i melt.. Right? Have a nice day both of you😊 Arne
How many hours of work did it take to do this? That's about 150 bucks in gold of course not counting materials, labor and silver that might also be recovered
I'm not sure if you have ever done it, but could you do as comprehensive a showing of all the equipment you use? I was thinking about starting a side hustle of refining once I get the ability to do so, and was curious about what you use.
Chris, I’ve included everything in my videos, leaving nothing out. But the first on my your list must be a fume hood. No way to do reactions safely without one.
Hello... i have a bunch of gold plated pins, moatly from pc parts. is it possible to skip d nitric or hcl boils and put them all in aqua regia? Thank you for your time and videos
@@sreetips I managed to gather up some pins... from what I can see... those are stainless steel pins... which acid should I use... hcl, nitric or something else... Thank You
close to $175 for that little button. I'd guess the gold value probably covered the cost of the costume jewelry, if it was bought right. That means any silver recovered later is near pure profit.
I think I'm at the nine 23 minutes point where you talk about dissolving the Silver leaving behind the Gold foil as you call it ,and I agree that the gold plating stays in the same form that it was on the jewelry but flatten out. Kind of fasinating I had success wiping or really dissolving gold off of white ceramic electronic boards and the back of a large cathode ray l tube . I wonder if the gold could be dissolved off of the silver. To minimize the amount of solution laden with precious metal nitrates. . Five gallon buckets of solution and large glass beakers are less desirable inconvientt than a small beaker/ Pyrex jar Aqua Rega dissolves gold plating immediately so I think it could be done on silver base metal quickly then rinsed off. I will watch the rest of the video to see how you handle the dissolved silver Wow @ The 30:19 he shows us perceptating the good out with a powdered chemical I'm not familiar with. Snd guess what ,? He was completely successful using his testing solution to verify that completeness I can't wait to see your yield of gold once this advertisement ends
They both contain the same amount of pure gold. White gold alloys use less copper and more white metals such as palladium, silver and zinc, to achieve a white color
@@sreetips An azeotrope is a (non-ideal) mixture of two or more components whose vapour phase has the same composition as the liquid phase. Therefore, it is not possible to obtain a mixture purer than the azeotrope in one distillation column.

Excuse my ignorance Mr Sreetips.

To burn off any grease, oil, or other junk that could cause ring-around-the-beaker.

They both contain the same amount of pure gold. White gold alloys use less copper and more white metals such as palladium, silver and zinc, to achieve a white color

Instead of using the MAP torch to 'burn off the people' have you considered boiling in sodium hydroxide solution to remove fats, oils etc.
That’s a possibility. But the torch is quick and easy.
