Gravity separation that can process pyrite is the separation that is according to the proportion difference between the pyrite and gangue which is associated with pyrite. The specific gravity of pyrite is higher and the specific gravity of gangue is lower. Through crushing and grinding, intergrowth structure in pyrite will be destroyed.

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).
