Fortune & Glory - Leaching gold

[randyclar747]

Something to do with Aqua regia, a mix of nitric and hydrocloric acids. Any idiot chemist knows this. This is nothing new, this technology.  In reality potassium cyanide, a deadly poison is used to professionally extract gold.

is kd-3 just stannous chloride?

[kurtnfredrickson]

I'm not sure exactly. You would have to ask the folks who make it, I just know it works. I think there's more info on their site about whats in the chemicals or at least an email address to contact them.

[mws123]

will this work on a larger scale of say 2-3 ounces at a time? for purifying gold?

[kurtnfredrickson]

I don't see why it wouldn't work. Large mining operations use chemicals to remove thousands of ounces. It seems to work best on micron gold. I had some larger pieces and it just ate away at them, but didn't dissolve them completely. To get a few ounces from micron gold, you would be looking at refining at an industrial scale. If typical ore has a gold content of say .2 grams per ton, it would take a lot of ore to get an ounce.

@metalicmario yeah the Kd-3 is just stannous chloride, really simple to make,. and the "acid solution" is aquaregia ,. is a mix of nitric acid and hydrochloric acid,.. is pretty foul stuff,. but you can search how to do it on the net,.

the "ball" of gold he has is not pure, as the Kd-3 drops all metal in the solution, it will have copper and the likes in it also,. you have to use certain chemicals to select certain metals to drop,. IE sodium chloride/table salt will drop only Silver

[kurtnfredrickson]

@mregier8039 Thanks for the extra info. I'm not a chemist, but I figured it was something like that.

good video

I would love to hear about your experiences and experiments with recovering gold from electronics.

[kurtnfredrickson]

I tried it on a cell phone and it doesn't work well. There are just too many metals and plastics that dissolve together. I recovered a small ball of something metal, but it was a mix of all the metals in the phone. In the end you get very little for a lot of work. Now if you could get old Intel chips, that would be different. There mostly gold plated.

[metalicmario]

this is awsome! have you tried it with anything like rings? if that worked you could sell 24k gold to jewelers for top dollar

[kurtnfredrickson]

I haven't tried leaching anything else, but the thought has crossed my mind. I actually just took apart a cell phone and collected all the gold connectors and plating. There was quite a bit. It's leaching now. If It works I'll put some details on my blog which can be accessed from my You Tube channel main page.

[metalicmario]

yeah keep me updated on this

[piecartbox]

There are a lot of little mom and pop companies that sell crucibles fluxes furnaces leach solutions testers etc for melting down and refining gold from scrap electronics/jewelry.

[piecartbox]

I looked at the test kit site and they seem to sell two kinds of leach solution, one they call Saturated salt and Nitric acid or SSN, the other is aqua regia or AR as they call it. I think they both contain nitric!

Imagine buying the chemicals in larger quantity, you could run a little leach vat plant out back lol.

[kurtnfredrickson]

The Gold Hunter Test kit site now explains what is in the KD1 leach. It is nitric acid based, but is diluted to a safe level. Happy leaching.

[piecartbox]

Heh yea it does not look like white fuming. Again thanks for the vids!

[piecartbox]

Sick, is that nitric + HCL?

Nitric can be bad stuff (high explosives are often made with nitric acid) so don't screw around with that one. HCL is stomach acid.

[piecartbox]

I'm interested to find out what kind it is.

This is a nice vid favorited!

[kingdonke]

Very cool however, I don't think I would do that indoors. What are the chemicals your playing with?

[kurtnfredrickson]

Safety is always a concern and this was done safely. The chemicals are 1, an acid solution and 2, a chemical that reconstitutes the gold. I don't have an exact name for them. They came with the kit.
