[QUOTE="Mike Marsupial, post: 391296, member: 11868"] I was reading today the HCL has no effect on gold. So, I was wondering how it would go cleaning up concentrates. I bought some at Bunnings and mixed it 50/50 with water and a couple of tablespoons of fine quartzy material. That was a few hours ago and not much seems to be happening. I also read that if I add vinegar with the HCL it will make any gold dissolve! Neat trick! Might use that a bit later if I get a place where I can make a decent workshop and do fancier stuff there. Cheers [/QUOTE]
