[QUOTE="Coyote, post: 105991, member: 1475"] Yeah I've had a bit of experience using Cyanide. You need activated carbon to adsorb the au from the slurry and then strip the au back out of the carbon, then electrowin the gold. dry the sludge and smelt with flux's. Not really that easy. I guess the other way may be to do a large bottle roll and filter the liquor and precipitate with zinc. I have never done this but from what I know it's fairly straight forward. Cyanide is a nasty if not handle correctly and the pH need to be kept high. Have a look on the net. Cliff [/QUOTE]
