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

About 38% of these are mineral separator, 16% are chrome ore, and 8% are crusher. A wide variety of chromite ore options are available to you, such as is concentrate, non-concentrate. There are 1,199 chromite ore suppliers, mainly located in Asia. The top supplying country or region is China, which supply 100% of chromite ore respectively.

The ball mill treatment reduced chromite grains greater than 15.77 µm down to sizes less than 11.15 µm in diameter, and thus released chromite-bound Cr(VI) for sulfide reduction. Magnesioferrite encapsulated Cr(VI) was released and reduced similarly with grain size change from 15.77 to 37.5 µm to below 15.77 µm.
