Silver Recovery from Silver Contacts

Recovering Pure Silver from Silver Contacts with nitric acid, hcl, lye and sugar. clean, drye pouring silver, silver bar casting

[@scrapman502]

I haven't seen an electric furnace look that new for YEARS! I'm on my second one, the first one met with a failed crucible and got turned into a copper art piece.

[@shaneyork300]

That was the coolest silver recovery video I have ever seen, and I've seen a hundred of them! When the HCL was being poured in the silver solution it made the coolest reaction! Have a Great Day!

Over the years i have saved a few contacts from larger contactors when scrapping equipment and bad parts. Have a few type R thermocouples to (platinum and Palladium Rhodium.

[@downyourtube]

Fair warning. If you send it out to refine, don't use "Midwest refineries" to do so. I sent them 5+ounces of the type R thermocouples and received a recording on my phone saying I sent copper (and it wasn't, I already had it verified). I lost money by sending it to them.

[@bobcansee]

[@ogbullion]

Thank you!

[@scrapman502]

one important step you may have left out was after converting the silver chloride to silver metal is to boil the silver in HCL. It will remove more contaminates like tin, and really clean off the rest of the lye and sugar.. It goes from Light grey color to a more silver like color. Much cleaner.

[@carlogarcia6792]

Does the tin paste contain tungsten

[@ogbullion]

No. But silver coated tungsten contacts have tungsten in them.

Great video. Got some questions you might could help with....So with nitric acid being rather hard to get if I make my own nitric would it be ok to make the acid with hydrochloric +potassim nitrate +copper and distill the acid off or should I use sulfuric acid in place of the hydrochloric? I'm thinking if it's hydrochloric formed nitric it would cause the silver chloride to precipitate out too early in the process... Causing problems with filtering the acid solution and washing the silver chloride.. Any help would be much appreciated

[@ogbullion]

sulfuric acid is a better choice, chlorine is likely to contaminate the acid. omegageek64 and nerdrage have helpful videos on the subject. Tanks for watching!👍

[@DarkMatterX1]

I actually don't understand the last part of this reaction. Could you explain the reaction between the sugar and the silver oxide lye solution? What is being exchanged? The output products are silver metal and what? And how is the waste disposed of? Thank you in advance for any reply.

[@ogbullion]

2AgCl + 2NaOH + 2e- (from glucose sugar) = 2Ag + O-- + H2O + 2NaCl. the waste non toxic, poured in the sink ,only the blue copper nitrate solution toxic, the copper solution goes to my waste treatment bucket with a piece of angle iron to cement out copper.

[@DarkMatterX1]

@@ogbullion Oh, I see. Thank you very much for your reply. I wasn't aware that the final output solution was non-toxic. I like that. The bucket with the iron in it is the same way I deal with my waste solutions. I keep the cemented copper to melt and repour to use again, both in silver reclamation and bronze alloying. I really appreciate you taking the time to reply. Not that it matters, but you've gained a new subscriber. Cheers man. 👍🏻

[@TheHoss4145]

Awesome video. But my question is: how do I get the silver part off the copper carrier material? I assume it's brazed on. Is there a trick?

[@ogbullion]

Thank you! I use a regular propane or mapp torch and pliers.

What do you do with the tin paste? Isn't tin worth further refining and melting down?

[@ogbullion]

[@TheRavensWing]

@@ogbullion I'd still be interested in seeing you melt down the tin paste into a tin bar.

[@youngcaesar5643]

Where do I find these contacts and what kind of equipment?

[@rastakillah3786]

I think those are mostly from relays, those need to have a precious metal for the connection, to preserve the quality of the connected side and the connection itself. Big ones coming from relays with high capacities, parameters, you find those pads right on the switch part of the relay.

[@mysterybuyer3738]

Those are big contacts compared to my little ones. How important is it to remove all of the brass arms? I cut them off but there is still a small brass or copper part attached. They are too small to really grab onto.

[@ogbullion]

Very very important to remove the contacts from the brass/copper. Copper need 2-3 ml nitric to dissolve 1 gramm, silver needs 1-1,5 ml nitric/ gramm( nitric acid very expensive), if you have silver in solution, and stil left undissolved copper in the silver nitrate, the silver starts to cement out on the copper.

[@mysterybuyer3738]

@@ogbullion Thanks I will see about separating them out further.

[@scrapman502]

If the arms are long enough, I would take vice grip pliers and hold them against a bench grinder and try to grind off as much copper from the back of the contacts as possible and then either break the contacts free from copper arms, or use a torch to melt the solder. Making the copper thinner allows the heat to do it's job. If not using a torch, it reduces the amount of acid needed to dissolve the contacts.@@mysterybuyer3738

[@pierreqiu8147]

Very interesting experience for me, but isn't it faster , easier, and save alots of chemical, just by diluting the solution with with lots of hot water after all the contact has dissolved and put in copper to bring out the silver foam, then dry and melt them.

[@ogbullion]

You don't need hot water to dilute the solution.And yes it's faster to cement out on copper, but the end product is 98-99 % pure, beacuse the copper main contamination, and I have to run trugh the silver cell to get .999 fine purity. With this chloride method I get .999 fine without bothering with the silver cell. Thanks for watching! 😉👍

Why not just use copper to cement out the nitrate? Less reactive. Very nice contacts tho. Great score

[@ogbullion]

Thank you! The answer is simple: Purity! If I cement out the silver on copper I only got 98% pure, with the chloride method I got 999. Pure silver. Also copper cement out led and platinum group metals along with the silver. Thanks for watching! 👍
