  • the role of magenisium oxide in ferrochrome production

Turkish Minerals

The ferrochrome is produced by electric arc melting of chromite, an iron magnesium chromium oxide and the most important chromium ore. Most of the world's ferrochrome is produced in South Africa, Kazakhstan and India, which have large domestic chromite resources. Increasing amounts are coming from Russia and China.

What's the Process of Iron Smelting? - Meetyou Carbide

In blast furnace, iron is not directly reduced from high valence oxide, but through a process of reduction from high valence oxide to low valence oxide, and then from low valence oxide to iron: Fe2O3 → Fe3O4 → FeO → Fe. The reduction of iron mainly depends on carbon monoxide gas and solid carbon as reducing agent.
