Magnetic Separation Of Ilmenite

on wet high intensity magnetic separators to recover ilmenite. The nonmagnetic fraction is subjected to gravity separation on spirals to produce a rutile/zircon rich concentrate. The concentrate is dried and then separated on electrostatic and magnetic separators to produce saleable rutile and zircon products.

Purifiion of ilmenite from chromite impurities by a two step magnetic separation wherein magnetically susceptible chromite is magnetically removed, followed by an oxidizing roasting of the ilmenite and a subsequent magnetic separation of ilmenite from the remaining chromite impurities to obtain an ilmenite with 1% or less chromite.

ilmenite is passed through a magnetic separation step in which the highly susceptible Cr2O3rich fraction of the ilmenite is removed. The remaining minerals containing Cr2O3 are not readily separable from the ilmenite by magnetic means since their magnetic susceptibility is almost identical to that of ilmenite.
