Fortune & Glory - Leaching gold

This is a test conducted with the Gold Hunter Test Kit. I recovered a small amount of gold from a very small sample. http://www.thegoldhunter.net/pages/testimonials.html

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

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.

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

@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

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.

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.

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

[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.

is kd-3 just stannous chloride?
