Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4 ). Chromite is the only ore mineral of chromium (Edwards, 2012). Further, in Balochistan, Pakistan, it occurs in in a rock series called the Muslim Bagh Ophiolite (Ahmad and Abbas, 1979). The major application of chromite is in production of stainless steel.
