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 21 is preferred, but ores with a lower ratio and as little as 40 percent Cr 2 O 3 are also used.
