Hi Folks
Just joined as I am hoping one of you knowledgeable folks can help me. I am wanting to know how to turn gold sponge back into free gold. That is fine micro gold that has been amalgamated in mercury, then put in the retort, resulting in a ball of gold sponge. Usually I melt this and then sell to a gold buyer. However I have received a request from a gold collector. Who desires, that the micro gold be free running. The gold is acquired from a blacksand beach claim and the only way to treat it is with mercury to recover it. I seem to recall that I read, years back that putting the sponge in either lemon juice or vinegar will do the trick. But thought I would check here first. Would be grateful if anybody can help. I am based in New Zealand on the west coast of the south island.
Cheers Trev.
