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.

Carbothermic reaction - Wikipedia

Of historic interest is the Leblanc process. A key step in this process is the reduction of sodium sulfate with coal: Na 2 SO 4 + 2 C → Na 2 S + 2 CO 2. The Na 2 S is then treated with calcium carbonate to give sodium carbonate, a commodity chemical. Variations. Sometimes carbothermic reactions are coupled to other conversions.
