Ilmenite HGMS for Minieral Separation

Through a series of research on ilmenite beneficiation, our technicists have made corresponding improvements in our magnetic separators since 1994. Firstly, for the low recovery rate of ilmenite, our technicists adjust the magnetic structure and magnetic field intensity, which increases the separation area and separation time.
