The only chromium-containing minerals that provide an industrial source of chromium are the chrome spinellids. In addition to chrome spinellids, the primary minerals of chrome ores are the silicates, including serpentine, chlorite, and sometimes olivine, pyroxene, plagioclase, uvarovite, chrome actinolite, talc, and brucite, and the carbonates and sulfides.
Potassium dichromate is a chemical reagent, used in cleaning laboratory glassware and as a titrating agent. It is also used as a mordant (i.e., a fixing agent) for dyes in fabric. Chromium (IV) Oxide (CrO2) is used to manufacture magnetic tape, where its higher coactivity than iron oxide tapes gives better performance. Chromium is used to harden steel, manufacture stainless steel, and form many useful alloys. It is mostly used in plating to produce a hard, beautiful surface and to prevent corrosion. Chromium gives glass an emerald green color and is widely used as a catalyst.
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 Cr2O3 and having a chromium-iron ratio greater than 2:1 is preferred, but ores with a lower ratio and as little as 40 percent Cr2O3 are also used.
