Case Study: Chromite mining and processing
commercially significant chromite mines include Russia, South Africa, Zimbabwe, Turkey, the Philippines and India.2 Chromite ore is initially concentrated prior to marketing by various processes depending on the ore source and intended end use.17 Chromite ore can be processed by grinding and heating in a furnace to about 1,100°C in a
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 chromium-iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3 are also used. (Ores high in alumina are preferred for …
