Chromium processing | Britannica

The use of chromite as a refractory is next in importance to the metallurgical applications of chromium. A typical analysis of a chromite suitable for refractory purposes is 38 to 48 percent Cr 2 O 3, 12 to 24 percent Al 2 O 3, 14 to 24 percent Fe 2 O 3, 14 to 18 percent MgO, and less than 10 percent SiO 2.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.Chromite: The only mineral ore of chromium metal,Beach sand rich in chromite and other heavy minerals is sometimes mined, processed to remove heavy minerals, and returned to the environment. Two facts allow these chromite sands to occasionally contain economic deposits of chromite.
