Chromite ore (FeOCr2O3) is the most important mineral occurrence of chromium, and some deposits are reported in Anka Local Government Area of Zamfara State.Chromium Wikipedia. For the production of pure chromium, the iron must be separated from the chromium in a two step roasting and leaching process. The chromite ore is heated with a mixture of calcium carbonate and sodium carbonate in the presence of air. The chromium is oxidized to the hexavalent form, while the iron forms the stable Fe 2 O 3.

    What is Chromite Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4).It is dark gray to black in color with a metallic to submetallic luster and a high specific gravity. It occurs in basic and ultrabasic igneous rocks and in the metamorphic and sedimentary rocks that are produced when chromite bearing rocks are altered by heat or weathering.Chromite, the only ore of chromium, was first discovered in the United States sometime about 1808 on the farm of Isaac Tyson, Jr., just north of Balti , Md. Scattered deposits of chromium minerals in an area of northeastern Maryland and southeastern Pennsylvania were the source of nearly all of the chromium products in the world between 1828.
