Chromite: The only mineral ore of chromium metal
Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4 ). It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite-bearing rocks are altered by heat or ...

Processing of Low-Grade Chromite Ore for Ferroalloy
The low-grade siliceous chromite ore from Ghutrigaon, Odisha, India, containing ~ 16% Cr2O3, with Cr/Fe ratio of 1.97 and ~ 55% of SiO2, does not find any use in metallurgical industry and hence considered as waste. Mineralogical investigation indicates the presence of chromite and quartz as major minerals with minor fuchsite and kaolinite. The …

CHARACTERIZATION AND BENEFICIATION OF ANKA CHROMITE ORE USING MAGNETIC …
5.0 Conclusion Magnetic separation is known to be more appropriate for treating fine particles. However, the greater tendency of the associated gangue materials to form dust more readily than chromite ore may be responsible for poor chromium recovery as the fineness of Anka chromite deposit increases.
