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 Otherwise, the transition visible at 40–50 K on the low-temperature magnetic susceptibility curves (Figure 7) could correspond to chromite as described by Gattacceca et al. in ordinary chondrite.

Carbothermic reduction roasting for processing of ferruginous chromite

Alteration of crystalline structure and magnetic property of these minerals enables separation of low-grade ore by using magnetic separation. It is found that low-grade ferruginous chromite ore can be upgraded by reduction roasting, and 61.2% Cr 2 O 3 was recovered with a chromium-to-iron ratio of 1.93 from a feed chromium-to-iron ratio of Usually, chromite ore enrichment is carried out by using gravity separation due to high-concentration criterion between chromite and other minerals.
