pyrite hematite magnetite

University of Minnesota's Mineral Pages: Pyrite

Despite being a common, iron-rich mineral, pyrite is rarely mined for its own sake, and most of our iron is produced from magnetite and hematite deposits. Those iron oxide minerals occur in larger concentrations and volumes than pyrite, so they are a more economical iron source.

Magnetite: The mineral Magnetite information and pictures

Magnetite may form a yellow-brown rust coating if washed or kept in a moist area. If a specimen is washed, it should be dried to prevent rusting. Rust can easily be removed by soaking the Magnetite in a rust-removing solvent such as Iron Out. The mineral Hematite is known to form pseudomorphs over Magnetite.
