Chromite Beneficiation Process
· Chromite Process Summary. This flowsheet is very effective due to the ability to remove the high grade chrome with very little grinding on each pass through the mill. In this way, grinding takes place with a large number of small reductions followed by immediate removal of the liberated chrome into a high grade concentrate.

Chromium processing
· Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its appliion as an electroplated

Extraction of Chromium from Chromite Ore
· The chromite grains in both samples were essentially liberated from the gangue at 100 mesh, although chromite was still locked with magnetite particles as small as 400 mesh. Both samples also contained fibrous structured minerals that may present environmental and/or health problems in the event of commercial mining and/or processing.
