chromite is a crystalline mineral composed primarily of iron(ii) oxide and chromium(iii) oxide compounds. it can be represented by the chemical formula of fecr2o4. it is an oxide mineral belonging to the spinel group. the element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (mgcr2o4). a substitution of the element aluminium can also occur, leading to hercynite (feal2o4). chromite today is mined particularly to make stainless steel through the production of ferroc · text under ccbysa licenseuses of chromium supply, demand, production, resourceschromite, an oxide of iron, magnesium, aluminum, and chromium, is the only ore mineral of chromium. in nature, chromite deposits are generally of two major types stratiform (layered) and podiform (pod shaped). both types are associated with ultramafic igneous rocks. the world's largest stratiform chromite deposits are found in south africa, in what is known as the bushveld complex.north american minerals corpchrome. formed with chris bathie of rio bravo alloys, north american minerals chrome sales, ltd. imports a wide range of chrome products, including metalurgical grade chrome ore, foundry sand chrome ore, chromic acid, basic chrome sulfate, sodium bichromate.miningweekly ferrous metals chromeby marleny arni 9th july lse and jselisted chrome and platinum miner tharisa delivered record mining and processing rates in the quarter ended june 30 the third quarter of the
