Chrome Ore (or Chromite) is an oxide mineral composed of chromium, iron, and oxygen.  It is used for Ferro Chrome production and in the refractory and metallurgical industries.  It is the basic material for magnesite bricks and compounds in the refractory sector.  It is also used as premium moulding sand in foundries and in the metallurgical industry.
