The CrFe 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 CrFe ratio has been reported.
Generally speaking, chrome ore contains a certain amount of iron, so the combined separation of gravity and magnetic separation is a relatively common chrome ore beneficiation process. It is surely that the specific beneficiation process should be determined according to the indicators obtained after the beneficiation test.
