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
