Chromite - Wikipedia

When chromite ore is mined, it is aimed for the production of ferrochrome and produces a chromite concentrate of a high chromium to iron ratio. [21] 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.
