How to Separate Specks of Fool’s Gold From Specks of Real Gold … Fool’s gold, the mineral pyrite, has a metallic luster and gray or black streaks, and feels heavy for its size, although real gold is denser
Pyrite and pyrrhotite often occur together creating an overlap in treatment methods Gold with Pyrrhotite Pyrrhotite readily reacts with cyanide to form cyanates and thiocyanates and it readily consumes oxygen Aeration with lime ahead of cyanidation is usually used on ores in this classification Aeration for preconditioning is used at Dome, Homestake, Kerr-Addison, and Pamour
