My material assays on average %4.0< Silver, %60.0 Copper, %10< Nickel, Please contact me if you can buy this material to refine regularly & payout around $20.00 CAD per pound. This material is silver filled solid dense material easy to handle which I’ve learned to find and sort out in large quantities. I’m a scrap gold & silver buyer so please do not waste my time with comments on its lack of value as I’m already getting paid on it but unfortunately the buyer gave me less than agreed which cost me thousands last time. I’ll entertain offers of at least %66.00 of the silver & copper combined value or %77.00 of the silver value alone, nickel will be free. I can provide other types of refining material as well. I’m located in Toronto you can pick it up or I can ship it out to you as well. Look forward to hearing from you guys thanks - Tom Cooper

So this is my first time trying to do gold recovery, and I have the Hydrochloric acid and bleach, and am wondering if I could safely mix them outside (because of chlorine gas) while wearing a respirator with gas cartridges and safety goggles, but want to be safe, (In a neighborhood)

I am looking for TCM processor modules from the IBM, Hitachi, and Fujitsu mainframes. I am working on a teaching demo related to mainframes and would like to be able to show examples of the technology. I would also be interested in any of the heat transfer equipment for these mainframes (cold plates, coolant hoses, connectors, etc.). I will pay above scrap metal value!

Any help would go a long way.

Dropped out a bunch of silver using a copper bar in silver nitrate solution. Poured everything through my filter, (upper right) discarded the copper nitrate solution, and was left with a wet pile a silver crystals and sludge, (in the beaker on the left).

Now I’ve been trying to wash out the remaining copper nitrate solution from my precipitate with boiling water, but it just won’t wash out. Every time I wash and discard, the solution still looks blue (lower right) and it looks like my sludge and crystals have bits of crystallized copper nitrate.

How do I remove the remaining copper nitrate?

I’m very interested in trying out a silver cell. That being said I’m not interested in dumping a ton of money in Pyrex, acid, a hood system, and dissolving my silver into solution. Is it possible to use a silver nitrate solution purchased online for a trial? If so what concentration would I need. If I like the process I’d buy all the needed stuff. I have 40oz of 97.5% pure silver tested with an XRF and 14oz of 925. Thanks!

I've been devouring sreetips videos but I don't even know where to begin. And I'm in a apapartment so some different challenges. But what's yalls suggestions for starting.

I’ve been recovering for about 7 months now and have about 2 Troy oz of fine flake. When I bought the foundry it came with ceramic crucibles but I invested in a graphite set as well. I’m hoping to pour into small coins or bars to save space.

Do I need to flux the graphite crucible pre melt like I would with the ceramic? Info online is spotty at best.

So i had 2 grams of 14K gold, I added 5 grams of scrap silver (925). I melted that together, put that in a beaker. When I added the nitric acid, the solution turned white almost instantly, after letting it sit a bit you can see that the solution is clear but there is this white precipitate. There should‘t be any tin in that, so my only guess is that the silver turned into silver chloride, can I use AR now, filter then SMB as silver chloride is insoluble in AP? Or better yet what would you do? Appreciate any help!

I’m thinking about experimenting with l adding a bit of sulfuric acid to nitric (maybe I’ll be able to save nitric or use more diluted nitric) to help it dissolve more silver but I’m worried about silver sulfate forming, does anyone know what happens as far as silver nitrate vs sulfate in that combination?

I know Nitric Acid will but Sulfuric acid is cheaper and easier to find so was wondering if Phirana solution ( Sulfuric acid+ peroxide would do the trick)

Hi! I have about 120 grams of inquarted gold that I need to refine and process, with an expected yield of 28-30 grams.

I have nitric & HCl, as well as sodium metabisulfite.

I do not have a fume hood or space in my apartment to make one. I do not have graduated cylinders, beakers, filters, funnels, etc.

If there are any refiners local to Los Angeles, would you be open to sharing your space? I'll give you 10% of my yield, + the silver chloride if you want it, for access to your fume hood & glassware.

Happy to jump on a call first too if you want to sus me out first!

I have a little over 400 grams of what was described to me by a relative who's since passed away, as an ore, with a large amount platinum in it that I'm interested in having refined and the metals in it possibly sold on ebay, to a refinery or perhaps at a local pawn shop. Below are photos of the material in a mortar used to grind the material and also in a bag containing around 200 grams of it. The material was sitting in a closet for around 8 years until a couple of months ago, when I decided to have the material tested by someone with an XRF machine Below are photos of the test results of several different samples in both General and Precious metals modes. The precious metals mode results indicate possible high concentrations of Iridium and Platinum, though I've read such machines often give false positives for Iridium and that the only way to be sure what you've got is by the assay method. In the general mode there's mostly bismuth. I'm in Southern Nevada near Las Vegas and when I did a Bing search for local businesses that might assay and process this material nothing came up. I called up a local refinery, but they said they only deal with businesses, not individuals like myself. There are a few businesses in other states such as Midwest Refineries that the Bing search engine indicated might be able to help me, but I have no experience doing this was wondering if anyone on this forum could suggest where to begin, as based on the XRF results this material could be quite valuable and I have no virtually no knowledge of refining methods myself. There's only 5 photos of the readings below, but I did several other tests with a couple of different machines and they all showed about the same percentages of platinum and iridium with the platinum consistently showing in the 30-35 percent range.

This is a switch from a communication device.

Could the community here he'll me get started? I've always been interested in this and would love to start. I just don't know where to begin. What sort of process is recommended? What equipment and ppe are required? Thanks

I have a bunch of 6/4 and beta-c titanium. Was wondering what the best process is to melt it down into 1LB bars .
