This is some sort of pyrite I bought the guy said this is the original rock called fools gold but...... He said there is a small amount of real GOLD in it
Fool's gold is iron pyrite. Iron pyrite is iron sulfide. Gold is many times associated with the sulfides. It is very possible your rock has both pyriite and gold. Some of the gold may be free milling or most likely bound in the pyrite. Gravity methods of recovery will not be suitible for the gold that is locked up in the pyrite. TTC
