How do you calculate iron pyrite?
An iron sulfide mineral with formula FeS2. The mineral pyrite (), or iron pyrite, also known as fool’s gold, is an iron sulfide with the chemical formula FeS2 (iron (II) disulfide).
What is the formula of pyrite?
FeS2
Pyrite has the chemical formula FeS2, meaning it is made up of one iron molecule, Fe, and two sulphur molecules, S.
Why is the formula of iron pyrite FeS2?
Iron has a valency of 2+ or 3+, so there are two iron sulfide molecules: FeS and Fe2S3. The first one is called ferrous sulfide and the other one is ferric sulfide. The sulfide ion has a valency of 2-, so the valency of iron in FeS is 2+.

How is iron pyrite formed?
Pyrite can be found in soils and sediments throughout the Earth as myriads of microscopic crystals. This pyrite is formed by bacteria that remove oxygen from sulfate in the water, producing sulfide that reacts with iron to form pyrite. More than 90 percent of the pyrite on Earth is formed by microbiological processes.

Iron disulfide. Iron sulfide (FeS2)
How much gold is in pyrite?
Pyrite as an Ore of Gold In some deposits small amounts of gold occur as inclusions and substitutions within pyrite. Some pyrites can contain 0.25\% gold by weight or more. Although this is a tiny fraction of the ore, the value of gold is so high that the pyrite might be a worthwhile mining target.
