Pyrite Mineral Uses and Properties

Pyrite and Coal Mining. Sulfur occurs in coal in three different forms 1) organic sulfur, 2) sulfate minerals, and 3) sulfide minerals (mostly pyrite with minor amounts of marcasite). When the coal is burned, these forms of sulfur are converted into sulfur dioxide gas and contribute to air pollution and acid rain unless they are removed from the emissions.
