Chromium (Cr) is a hard, bluish metallic element. The only ore of chromium is the mineral chromite and 99 percent of the world's chromite is found in southern Africa and Zimbabwe. Geologists estimate that there are about 11 billion tons of mineable chromite ore in the world, enough to supply the current demand for hundreds of years.
Get PriceChromite is important because it is the only economic ore of chromium, an essential element for a wide variety of metal, chemical, and manufactured products. Many other minerals contain chromium, but none of them are found in deposits that can be economically mined to produce chromium.

Get Price/EPIDEMIOLOGY STUDIES/ Hexavalent chromium is a known carcinogen. Previous epidemiologic studies in the 1950s of United States workers from seven facilities producing chromium compounds from chromite ore have reported a markedly increased risk for dying from lung cancer.
Get Pricechromite (krō´mīt), dark brown to black mineral.It is an iron-chromium oxide, FeCr 2 O 4, with traces of magnesium and aluminum.Its crystals are octahedral, but rare; it usually occurs as irregular, granular masses in association with igneous rocks, including ophiolites, which are segments of oceanic crust exposed on land by tectonic processes usually associated with plate convergence (see ...
Get PriceChromite, 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 ...
[PDF]Get PriceChromite, the principle ore of the element chromium, is a commercially valuable mineral. However, due to mining restrictions and the fact that Chromite is not commonly found in crystallized form, it is not well-represented in mineral collections.
Get PriceAn ore is a natural occurrence of rock or sediment that contains sufficient minerals with economically important elements, typically metals, that can be economically extracted from the deposit. The ores are extracted at a profit from the earth through mining; they are then refined (often via smelting) to extract the valuable element, or elements.. The ore grade, or concentration of an ore ...
Get PriceThe carbothermic reduction of chromite ore to produce high carbon ferrochromium is among the most energy intensive metal extraction processes performed, due not only to the highly endothermic nature of the reduction reactions but also the very high operating temperatures required for the smelting operation to separate the chrome-containing alloy from the discard slag.
