22.4: Beneficiation
The iron ore magnetite, Fe 3 O 4, is ferrimagnetic. It can be separated from abundant deposits of taconite by grinding to a fine slurry in water. Passing this suspension over powerful electromagnets removes the Fe 3 O 4, more than doubling the concentration of Fe. Both the physical beneficiation processes just described produce large quantities ...
