The smelting of chromite to produce ferrochrome (FeCr) and subsequently, stainless steel, is an energy-intensive carbothermic process. Various countries apply the Outotec FeCr process, which employs oxidative sintering in air to produce mechanically strong chromite pellets. During this process, iron (Fe) is liberated from the chromite spinel due to the elevated …
The Kemi chromite mineralization was discovered in 1959 and mining commenced in 1968. The mine's current proven ore reserves total 50.1 Mt with an average grade of about 26.0% Cr 2 O 3 and a chrome–iron ratio of 1.6–1.7. Additional mineral resources, which have been estimated to a depth of 1 km, comprise 97.8 Mt (Outokumpu, 2014).
