Hello. Who knows what was used to dissolve the gold in the video? This rapid and non-toxic.

Sorry for my English, thank you for your understanding.
 
Cyanide is a lot of things, and used correctly it is safe however there's one thing it cannot be described as and that's non toxic. Especially the way smoking joe is using it. 8) 8)
 
That is reckless, cyanide will be absorbed through the skin. How much is another question.

A clear case of when a little bit of knowledge is dangerous.

Not quite that bad Goran. Miners in hot countries would (and allegedly still do) swim through the leech tanks to cool off with no ill effects.

I'd be more worried about the leeches. :lol:

Teasing English English aside, at typical concentrations used in leaching swimming through it is more likely a hazard to the eyes from the alkali than toxicity. I'm more worried to get caustic in the eye than even sulfuric! Perhaps the rabbit tox test was done with a very basic solution that broke down the skin and allowed it into the vascular system or else it is very slow to penetrate.

Maybe the leach is thiosulfate?

Care to elaborate on that?

What is he using then? What should the title be?

I don't speak Thai so I can't understand what he is saying in the video.

The description (loosely translated) is "Teaching materials extraction of gold from gold plating without cyanide or acids of any kinds. And no pollution to the environment and yourself."
You can be taught the process for 4000 Baht (a little over $100 U.S.).
