20 Comment on iron ore aggregate illmanite hemitite magnitite

Does anyone know a good replacement mineral for Hematite that.

As Mr Harald Said, What is the fundamental idea for substitution of Hematite? although some consideration must be to do for substitution of Hematite by Magnetite. One of them is the Fe++ Iron content into the Magnetite, but if you want to recover the Iron content you might use some process according to that, and other.
