Chromite is the commercial name for iron chromium oxide (FeCr2O4), a mineral containing chromium (a transition metal with multiple oxidation states) and iron oxide. In its purest form, chromite comprises chromium (Cr2O3) at 68% and iron oxide (FeO) at 32%. Chromite occurs exclusively in ultramafic rocks such as dunite,
Chromite is a mineral and can be described as an iron chromium oxide, with a 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 second trader said downstream demand for chromium chemicals for all appliions was high and costs were increasing. "There has been a cutback in sodium dichromate in Argentina, which is the mother chemical from which all chrome chemicals are produced, such as chrome oxide, chromic acid and basic chrome sulphate," he said.

What is Chromite? Chromite is an oxide mineral composed of chromium, iron, and oxygen (FeCr 2 O 4) 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 chromitebearing rocks are altered by heat or weathering.

Chromite has a variety of uses. Chromium is extracted from it to make stainless steel and other alloys for which resistance to oxidation and corrosion is important. Chromium is also used as plating and tanning agent. The mineral chromite is made into refractory lining for steelmaking furnaces.
Chromite (Fig. 1.12) is an iron chromium oxide (FeO,Cr 2 O 3 or FeCr 2 O 4 ± Mg). In its purest form, chromite ore contains 68% Cr 2 O 3, and Cr:Fe ratio of 1.8:1. Louis Nicolas Vauquelin was the discoverer of the element "chromium," and named the mineral "ferrouschromatealumine" in 1798.
Commonly it is found in numerous ores, usually in the mineral chromite. Chromite is the complex of (FeCr_2O_3), or iron chromium oxide. Chromium is also found in other minerals, including magnesiochromite ((MgCr_2O_4)). Chromite is found in earth''s mantle and is mined most abundantly in South Africa, India, Kazakhstan and Zimbabwe.
Chrome Alumina is produced by fusing high purity calcined alumina and chromium oxide. The end product has excellent hardness and resistance properties.
Aluminothermic production of high purity chromium metal accounts for over 95% of chromium metal produced today. The first step in this process requires that the chromite ore is roasted with soda and lime in the air at 2000°F (1000°C), which creates a sodium chromate containing calcine can be leached away from the waste material and then reduced and precipitated as chromic oxide (Cr 2 O 3).
oxide, with a chromium:iron ratio of not less than 3:1. Silica should be low and combined alumina and magnesia should be less than 25 per cent. chromite as a refractory has a high resistance to corrosion and thermar changes and has a neutral character towards slags. Refractory grade chromite should have over 57 per cent of total chromic and
Chromium. 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.
Chromite, iron magnesium chromium oxide: (Fe, Mg)Cr2O4, is an oxide mineral belonging to the spinel group. Magnesium is always present in variable amounts, also aluminium and iron substitute for chromium romite is found in peridotite and other layered ultramafic intrusive rocks and also found in metamorphic rocks such as serpentinites.
Chemicalgrade chromite ore generally ranged from 40 to 46 pct Cr2O3 with a chromiumtoiron ratio of 1.5:1 to 2:1. Refractorygrade chromite ores contained a minimum of 20 pct Al2O3 and more than 60 pct Al2O3 plus Cr2O3.
