[QUOTE="Heatho, post: 68271, member: 487"] The old timers used to roast sulphides out, seeing sulphur dioxide is toxic there is supposedly another way. Crush your sulphide ore to a fine powder and keep moist for about 1 year, bacteria and oxygen will/may release gold from such minerals. Can't remember where I found the article but it is on the WWW somwhere. Yes pyrites and other similar minerals can and do contain gold but extraction is the hard part. Peroxides, acids and Cyanide can also do the job but........ getting extremely dangerous for a novice, which is why most of us amatuers only go for Gold which is already free in nature. [/QUOTE]
