Chromium Ore - an overview ScienceDirect Topics

Chromium Ore Chromium ores are often classified based on their elemental composition and industrial use into: high-chromium (46–55% Cr2O3, Cr:Fe >2.1) used for metallurgical processes, high-iron (40–46% Cr2O3, Cr:Fe 1.5–2.1) used for chemical and metallurgical purposes, and high-aluminum (33–38% Cr2O3, 22–34% Al2O3) used widely as refractory material [1].

Chromite Ore - an overview ScienceDirect Topics

Chromium is mined—as its ore “chromite”—in South Africa, Kazakhstan, India, Russia, and Turkey. Almost 90% of chromium is accounted for in the production of steel alloys (including “stainless” steel) or in electroplating. Other uses include in tanning where trivalent chromium salts such as chrome alum cross-link collagen fibers, so stabilizing the leather. Chromite has high heat resistance and is used in

Chromite - Wikipedia

Chromite is a crystalline mineral composed primarily of iron oxide and chromium 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. A substitution of the element aluminium can also occur, leading to hercynite.
