  • 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.Chromite is found in peridotite and other layered ultramafic intrusive rocks and also found in metamorphic rocks such as serpentinites. Ore deposits of chromite form as early magmatic differentiates. It is commonly associated with olivine, magnetite, serpentine, and corundum.
  • Although its primary origin is ultra-mafic rocks such as peridotites, chromite is also found in metamorphic rocks such as serpentites. Chromite, as is indicated by its early crystallization is resistant to the altering affects of high temperatures and pressures. Thus it is capable of going through the metamorphic processes unscathed, while other minerals around it are being alteres to serpentine, biotite and garnets.
  • The processing of chromite ore is associated with the generation of large quantities of solid wastes containing chromium, which have been disposed of as landfill for many years. The mobilization and operational speciation of chromium contained in soils contaminated with metal salts are important in terms of the environment. Several methods have been employed for the extraction and recovery of solid wastes.
  • Application of selective flocculation using starch to separate chromite from serpentine has been investigated. It was determined that starch has a specific affinity towards chromite which can be exploited in selective flocculation. However, it was found that this could only be achieved when the amount of serpentine in the chromite-serpentine mixture is below 30% by weight and in the presence of a dispersant such as sodium silicate or ultrasonic treatment of the pulp.
  • Chromite is seldom used alone. It is the supreme additive, endowing alloys or materials with new properties: strength, hardness, permanence, hygiene, colour and resistance to temperature, wear and corrosion. This versatility has made chromium indispensable in countless everyday applications. The primary commercial supply is in the form of chromite ore or ferrochromium for the ferrous and non-ferrous metals industries, the chemical industry and the refractories industry, which has a direct application for chromite as a heat conductive foundry moulding sand.
  • Chromite is the most important ore of chromium from which it derives its name. Chromium is an important metal and has a wide range of industrial uses. Chromite forms in deep ultra-mafic magmas and is one of the first minerals to crystallize. It is because of this fact that chromite is found in some concentrated ore bodies. While the magma is slowly cooling inside the Earth's crust, chromite crsytals are forming and because of their density, fall to the bottom and are concentrated there.
  • Chromite mineral is the source for chromium metal. Chromite deposits are found at Nakiloro and Lolung in a belt 6 km long north of Moroto town. The chromite here is associated with platinum, a precious metal. There has been no chromite production to date in Uganda.Chromium is used in making special alloy steels and for chrome coating. Chromite as an industrial mineral is used in metallurgical processing and in furnaces as a refractory.
  • Chromite mining in India started around 1903 there was no ferro-chrome production in the country till 1968. Hence most of the chromite ore was exported. India exported about 3.84 million tonnes between 1903 to 1980. The current production rate of chromite ore in the country is between 0.7 to 0.9 million tonnes per annum. In 1986, India attained a production of 90,000 tonnes of FeCr/charge chrome. Prior to implementation of the OMCAL, and FACOR units, the production of FeCr was only about 20,000 TPA. The situation has changed dramatically due to the commencement of production in the export oriented units.
  • Tata Steel Ltd. and Orissa Mining Corp. Ltd. proposed a joint venture on chromite mining in the Sukinda Valley in Orissa. Orissa Mining held more than 80% of the mining lease in the valley, which totaled 4,700 hectares;Tata Steel held 406 ha.
