Processing of Low-Grade Chromite Ore for Ferroalloy ...

2020-7-14  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 beneficiation studies reveal that the product can ...

「chromite mineral processing technique」

Chromium processing Britannica. Chromite deposits are mined by both underground and surface techniques. Much of the ore is rich enough to be used directly: for production of ferrochromium, a rich, lumpy ore containing more than 46 percent Cr 2 O 3 and having a chromiumiron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3
