Pyrite Mineral Uses and Properties
Iron is typically obtained from oxide ores such as hematite and magnetite. These ores occur in much larger accumulations, the iron is easier to extract and the metal is not contaminated with sulfur, which reduces its strength. Pyrite used to be an important ore for the production of sulfur and sulfuric acid.
