Magnetic separation studies on ferruginous chromite

2015-3-4  The Cr:Fe ratio (chromium-to-iron mass ratio) of chromite affects the production of chrome-based ferroalloys. Although the literature contains numerous reports related to the magnetic separation of different minerals, limited work concerning the application of magnetic separation to fine chromite from the Sukinda region of India to enhance its Cr:Fe ratio has been reported.

This procedure consists of magnetic separation in two stages, i. e. at a magnetic field strength of 5000 and at 11000 oersted. The concentration of chromite ore from the Kempersayi deposit according to the above procedure permits a decrease of SiO 2 (from 6.1 to 2.5% and CaO (from 1.3 to 0. 7%) and an increase of Cr 2 O 3 (from 51.7–52.3 to 55.6%).
