Ferrochrome - Wikipedia

Ferrochrome, or Ferrochromium (FeCr) is a type of ferroalloy, that is, an alloy between chromium and iron, generally containing 50% to 70% chromium by weight.. Ferrochrome is produced by electric arc carbothermic reduction of chromite.Most of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources.

Chromium processing | Britannica

Chromium processing, preparation of the ore for use in various products. Chromium (Cr) is a brilliant, hard, refractory metal that melts at 1,857 °C (3,375 °F) and boils at 2,672 °C (4,842 °F). In the pure state it is resistant to ordinary corrosion, resulting in its application as an electroplated
