Smelting - Wikipedia

Smelting is a process of applying heat to ore in order to extract a base metal.It is a form of extractive metallurgy.It is used to extract many metals from their ores, including silver, iron, copper, and other base metals.Smelting uses heat and a chemical reducing agent to decompose the ore, driving off other elements as gases or slag and leaving the metal base behind.

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.
