Chrome Ore

Chrome ore is an indispensable mineral resource for metallurgical industry, chemical industry and national defense. It is used in the hardening of steel alloys and the production of stainless steel, in corrosion-resistant decorative platings, and as a pigment in glass. The chrome ore is found principally in South Africa, Kazakstan, Zimbabwe, Finland, India, Turkey and Algeria. China has a limited resource of chrome ore, mainly distributing in Tibet and Sinkiang.

Production
In Pakistan, Chromite is mined from the ultramafic rocks in mainly the Muslim Bagh area of Zhob District of Balochistan. Most of the chromite is of metallurgical grade with Cr2O3 averaging 40% and a chrome to iron ratio of 2.6:1. Afghanistan has significant deposits of high grade Chromite ore.
 
Recently, the biggest user of Chromite ore has been China, importing large quantities from South Africa, Pakistan and other countries. The concentrate is used to make ferrochromium, which is in turn used to make Steel.
