Chromite Chromium Ore, Properties, Uses and
Chromite is an oxide mineral that an iron chromium oxide with formula: FeCr2O4 It is belonging to the spinel group Chromite is the most important ore of chromium Crystals are uncommon, but when found they are octahedral Chromite is usually massive or in the form of lenses and tabular bodies, or it may be disseminated as granuleschromite (krō`mīt), dark brown to black mineralIt is an ironchromium oxide, FeCr 2 O 4, with traces of magnesium and aluminumIts 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 Chromite Article about chromite by The Free Dictionary Chromite This mineral is iron chromium oxide, and the only significant ore of chromium, a valuable strategic metal Chromium deposits worldwide are not common, although chromium appears as an impurity in a large number of minerals Chromite is always black and occurs both as sharp octahedral crystals and as granular masses (seen here)Chromite Stock Image C013/9427 Science Photo

Chromite is a crystalline mineral composed primarily of iron(II) oxide and chromium(III) oxide compounds It can be represented by the chemical formula of FeCr 2 O 4It is an oxide mineral belonging to the spinel groupThe element magnesium can substitute for iron in variable amounts as it forms a solid solution with magnesiochromite (MgCr 2 O 4) [5] A substitution of the element aluminium Studies on solidstate reduction of chromite have shown that the iron oxides get reduced more readily than the chrome oxides Under such conditions, iron forms only one carbide Fe 3 C, which can dissolve chromium to form a complex carbide (Cr,Fe) 7 C 3 Thus, an ore rich in iron oxide will have high reducibility at relatively low temperaturesChromium Ore an overview ScienceDirect Topics metallurgical industry for manufacturing of stainless steels and chromiumcontaining metal alloys [6] Ferrochromium is produced by smelting of chromite ore in reducing atmosphere in an arc submerged furnace with coke at high temperatures (above 1600oC), with partial solid state prereduction of chromite The reduction of chromium oxide takes A Cr⁶⁺⁻ Free Extraction of Chromium Oxide from Chromite
