How Is Pyrite Formed? |

A: Pyrite forms due to a chemical process initially caused by the decomposition of organic matter in bacterial sulfate reduction. The bacterial sulfate reduction produces an inorganic anion known as bisulfide, which reacts with iron minerals to form iron sulfides, the most common of which is pyrite....

Iron Ore Statistics and Information

Iron ore is a mineral substance which, when heated in the presence of a reductant, will yield metallic iron (Fe). It almost always consists of iron oxides, the primary forms of which are magnetite (Fe 3 O 4) and hematite (Fe 2 O 3). Iron ore is the source of primary iron for the world's iron and steel industries....
