    Chromite ore can be mined to produce chromite concentrate. It can also be crushed and processed. Chromite concentrate, when combined with a reductant such as coal or coke and a high temperature furnace can produce ferrochrome. Ferrochrome is a type of ferroalloy that is an alloy in between chromium and iron. This ferroalloy, as well as chromite concentrate can introduce various health effects. Chromite oreis found in underground conditions. Therefore, when exposed to aboveground conditions,

  • Ferrochrome - Wikipedia

    Ferrochrome, or Ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy between chromium and iron, generally containing 50% to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of chromite.Most of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.

    The production of high carbon ferrochrome is a reductive process, and as such changes the oxidation state of the chromium in natural chromite from the plus 3 (Cr3+) oxidation state to zero. Unreduced chromium in the slag is in the 3+ state, which is chemically very stable. With the older semi-closed processes, some hot dust can be subjected to oxidation and under certain circumstances small ...

  • Chromite: The only mineral ore of chromium metal

    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.
