Basic AMD Chemistry - Lehigh University

Basic AMD Chemistry: There are four commonly accepted chemical reactions that represent the chemistry of pyrite weathering to form AMD. An overall summary reaction is as follows: 4 FeS 2 + 15 O 2 + 14 H 2 O => 4 Fe(OH) 3 ¯+ 8 H 2 SO 4 Pyrite + Oxygen + Water => "Yellowboy" + Sulfuric Acid. The first reaction in the weathering of pyrite ...

Pyrite | Minerals Education Coalition

Pyrite. Commonly called fool's gold, pyrite is the Earth's most abundant sulfide mineral. Recognized for its brass-yellow color which resembles that of gold, pyrite is a source of iron and sulfur and is used for the production of sulfuric acid. Some types of pyrite contain enough microscopic gold to warrant mining them as a gold ore.

It has the chemical formula CuFeS 2.It has a brassy to golden yellow color and a hardness of 3.5 to 4 on the Mohs scale.Its streak is diagnostic as green tinged black.

Molecular weight of pyrite - Convert Units

When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. If the formula used in calculating molar mass is the molecular formula, the formula weight computed is the molecular weight.
