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
