Chromium (Cr) Ore | Minerals, Formation, Deposits
Smelting: Once the chromite ore is concentrated, it is then smelted to produce ferrochrome, which is a key alloying element in the production of stainless steel. Smelting involves the reduction of chromite ore in the presence of a carbonaceous material (such as coal or coke) in a submerged electric arc furnace or a blast furnace. The high ...
