Chrome Ore Sand is an Iiron chromium oxide found naturally in the earth crust, obtained by underground mining. It is by far the most industrially important mineral for the production of metallic chromium, used in the production of stainless steel and tool steel. It is also used as a refractory material because of its high heat stability.
