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.

OverviewOccurrencePhysical propertiesChemistry and compoundsHistoryProductionApplicationsBiological role

Chromium is the 21st most abundant element in Earth's crust with an average concentration of 100 ppm. Chromium compounds are found in the environment from the erosion of chromium containing rocks, and can be redistributed by volcanic eruptions. Typical background concentrations of chromium in environmental media are atmosphere lt;10 ng/m ; soil lt;500 mg/kg; vegetation lt;0.5 mg/kg; freshwater lt;10 g/L; seawater lt;1 g/L; sediment lt;80 mg/kg.
