A novel method for efficient recovery of ilmenite by high gradient
The ore was ground firstly to realize the liberation of ilmenite from residual magnetite, with the particle size below 0.074 mm accounting for 85%. Weak magnetic separation was conducted to remove residual strongly magnetic magnetite for avoiding serious magnetic aggregation in HGMSCMF process. The final sample assayed

Magnetite Concentration Methods
Pyrrhotite (Fe7S8, sp. gr. 4.5 to 4.65) is, on the other hand, usually ferromagnetic, and is drawn into the magnetite concentrate. It is not so strongly magnetic as magnetite, and sometimes a partial elimination is accomplished; but, generally speaking, it may not be removed from magnetite by magnetic separation.
