Ferrochrome (FeCr) – Mineral-Loy

Ferrochrome Ferrochrome (FeCr) is an alloy of chromium and iron, generally containing 48 to 70% chromium by weight. It is produced in an electric arc furnace by the reduction of chromite ore. South Africa has the largest reserves of chromite ore and is also the world’s largest producer of Ferrochrome with most production being exported to China.
