What is Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral.

For large tonnages, big commercial mines oxidize their pyrite in roasters or autoclaves. This is very expensive equipment, costing many millions of dollars. It is only justified for the biggest operations. Once the pyrite has been oxidized and the sulfur driven off, the remaining iron oxide material is treated by cyanide to recover the gold.

Iron pyrite is a naturally pure and hugely useful ore of iron, finding applications in areas as diverse as photovoltaic cells, brake pads and as a glass colourant. African Pegmatite is a leading supplier of iron pyrite, with the ability to provide the material in a range of grind sizes suited to any operational need.

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).

What is Pyrite? Pyrite is a brass-yellow mineral with a bright metallic luster.It has a chemical composition of iron sulfide (FeS 2) and is the most common sulfide mineral.It forms at high and low temperatures and occurs, usually in small quantities, in igneous, metamorphic, and sedimentary rocks worldwide. Pyrite is so common that many geologists would consider it to be a ubiquitous mineral.
