Pyrite In The Manufacture Of Iron | African Pegmatite

Pyrite is not regarded as a good source of iron itself, especially compared to magnetite and hematite despite being approximately half iron by weight but it is a good source of sulfur(1). The addition of materials such as pyrite to molten/cast iron is referred to as inoculation, and is a common liquidstate treatment of the iron(2).
