Extraction And Processing Of Pyrite

Extraction And Processing Of Pyrite. The pyrite in which small amounts of gold occurs is of crystalline variety primary pyrite. The characteristics of primary pyrite are a absence of porosity, an extreme brittleness, a resistance to oxidation, and the existence of gold possessing a weak susceptibility to magnetism due to a fine coating of a iron compound.
