It seems that a lot of time, effort, and reagent (nitric acid) goes into removing the residual silver shot. I know you’ve tried rinsing off the material with distilled water in a sieve without much luck. Have you thought about using your ultrasonic cleaner with just water to try to physically remove the PGMs from the residual silver rather than dissolving it all with nitric? Worst case, you end up with a watery mess like you had in your beaker before adding acid; best case, you can return the cleaned silver shot to the silver cell, and proceed with just the slimes to dissolve. Thanks for making these videos, I’ve been enjoying them for a couple of years.
Well, if he puts the filters in an ultrasonic cleaner he'll get the same soup except the filters will probably be very clean. I'm suprised at how little the filters react with the acid (which is great). If I were in Sreetips (comfy leather) shoes I wonder if I wouldnt want to try cyanide leaching from the filters, just to see if there are additional PGM's there.
Thank you sir. I love to see your process for Ag slimes. Its nice to see a full clean up of the work. And the slimes is definitely the most troublesome, ok and Pt.
Hello mr. Sreetips, I now very little about refining precious metals, but I watch all of your videos! I assume it isn’t possible to have a “gold cell” and use the same process to make pure gold crystal? Just curious as to why not? Thanks
@@MerchantMarineGuy Why would you want to silver plate a gold plated bowl? The object here is to place the high purity silver into solution. Watch part II the silver will precipitate out of solution with a few spoons of sodium metabisulfate. Maybe we'll see an addition of sulfuric to flash off any lead. The copper tab used as the cathode just improves the electron flow into the electrolyte; it is a good conductor.
@@anthonyrstrawbridge He isn't talking about silver plating a gold plated bowl. He's wondering if by using a stainless steel bowl that has been gold plated would it work in the original posters question to which he replied. (Re: A gold cell to make pure gold crystals)
As always Sreetips, great vid, when will you be doing the bigger silver cell? will be interesting to see if the process is different such as amps and volts for the larger amount of silver used
I’ll be building a second silver cell. But it will probably be about the same size as my current design. This is due to the critical distances that must be maintained between the anode filter basket and the cathode - about 4.5 inches
@@sreetips Im going to try an 11 litre one, I will let you know how I get on, I will keep in mind the distance from cathode to anode, and try the same volts and amps as the smaller one with 150g of silver per litre, if it doesnt work then I will go back to the smaller cathode and anode which I have had relative success with
nice series, been waiting for it. just a general question: would it be an idea to use some filter made from paper/nonplastic for your filter baskets? then you could use sulfuric acid to dissolve them and refine that in more or less one go.
hi mr. sreetips, i have a question did you ever processed golden industy needles(not medical needle)? they are used to test uniformity on sufraces and such. i bought almost a kilo of those off of ebay for 100$ but im not sure if they are real gold. it gonna the firat time
How can you tell if your electrolyte is spent? Because I have read that there becomes a point that you are making impure crystals. I would hate to be wasting my time but also not having to make a new batch of silver nitrate EVERY TIME. Thanks. Love your vids, you've taught me almost everything I know about refining.
I use mine twice maximum. And for the second use I add 200g more silver to augment silver concentration. I used it three times once. It was almost pure copper nitrate. The silver crystals were big and fat. But they had green on them. The electrolyte was so devoid of silver that no silver chloride precipitated out when I added HCl. I was baffled but learned my lesson. Never use it more than twice. And always augment on the second use.
I was wondering the same until I realized that the object here is to process the high purity silver because the status test didn't reveal a strong positive indication of the platinum group.
@@anthonyrstrawbridge incineration is cheaper and works just fine but there are more time costs setting up a whole nother process and ash or fiber you still have to use acid in the end to recover the gold he might get four or five grams of gold
It might be an easier first step but I would be concerned about the potential for values to be burned off as some sort of volatile compound. by doing the filters wet it would negate that chance.
I was considering firing up my propane furnace and just tossing in the filters and melting everything into an alloy then pouring into water to form granules. But I chose not to do it because I wasn’t certain of how it would come out. I may experiment with just a single filter in the furnace for next time.
I know this isn't worth the time or money to do, but I'm curious. Can you set up copper cell with copper nitrate and it works the same as the silver cell?
Would recommend to use a rather corse strainer (wet classification) to reduce the amount of silver as these beads are much corser than that slime. Would reduce time , money and waste of chemicals
Yes classification is always better than repurification. A rigid (avoid mesh ones - too difficult to clean) stainless steel chinois (conical strainer or Chiense strainer) should be used and the residual silver shot washed with steam into a beaker. The remaining silver shot can then be dried and returned to silver cell.
@@hansmaier608 You need a very very strong stir bar to move silver powder around.... With the added distance of the porcelain container I'm not sure that's possible. When you have small amounts of silver you can get away with it by removing the silver from the center of the beaker so it keeps being pushed around by the vortex and not getting the stir bar stuck but for the amount I see in that beaker I wouldnt even try it.
@@sreetips I respect what you do Sir. The danger is what makes me think twice making this happen. Second, I am surprised that you only use real low electric current for the reduction of a particular element. The reason is I just can't wrap my mind around that this works. Tip my hat off to you Sir. Look forward to watch more videos from you. Peace fella too.
Sreetips fun fact here. That orange smoke also is present when ammonia nitrate based blasting agent is used aka ANFO. It only shows up when a blast has not fully propagated. It is poison but it smells like money to me and I quite like it.
Is it really a solution of silver cyanide AgCN ? Or silver nitrate solution? Действительно ли это раствор цианида серебра AgCN? Или раствор азотнокислого серебра?
It's a Silver Nitrate solution. Safer to handle because no risk of hydrogen cyanide being produced, and both easier and probably cheaper because he's already got the materials for making the electrolyte anyways.
I think, that it would be better to rinse out any large leftover silver shot pieces (using the sieve) and smelt them down for refining in silver cell. You should refine only the black "slime", saving a lot of nitric acid in the process. In other words, the black stuff, stuck on the leftover silver shot, is not worth the nitric acid, that is used to dissolve the leftover silver shot. ;)
Slime is exiting ! It makes the saying "One's man trash, another's man treasure" very true. It's not specific to silver refining. Slimes usually are smelly, and look like mud. In copper refining, anodes are usually around 92% copper. When you know there's gold and other precious metals in there the slimes can be an important part of your income.
Yes, but be careful. As the metals rise in price folks will be turning out fakes. Nothing worse than discovering that your hundred ounce silver bar is really silver plated copper!
The bottom of it has kind of a copper color to it. The whole thing is tarnished Purdy bad too. Plus I jus bought a 33 gram 18k gold bracelet that turned out to be a fake gave a thousand dollars for it and now I'm leary bout buying anything that big is why I ask.
@@sreetips At the very worst you could put the ashes back to be dissolved with silverware. You can even put a bit of Borax to collect everything and dissolve it aswell in the acid. Those few sodium and boron ions just be spectators compared to the lead, tin, zinc and sometimes iron you find alloyed with silverware.
the silver sludge paste in the basket of the electrolytic cell is the anode silver metal, and the electrolyte (the liquid in between the electrodes) is a solution of silver cyanide, AgCN, in water. When the direct current is passed through the cell, positive silver ions (Ag+) from the silver cyanide migrate to the negative anode, where they are neutralized by electrons and stick as silver metal. The anode basket sludges gradually dissolve to replenish the silver ions in the solution. The result is that silver metal has been transferred from the anode to the cathode. 😁
Where does Sreetips get your Nitric Acid from. You use so much, I'm trying to find a company so I can refined larger amounts of materials but don't have a provider or company connection to go to.
I buy from gfs chemicals. But you must have a business address for shipping. My last order was $300 for six 2.5 liter bottles delivered. Probably higher now due to money printing.
