Pilot plant production of ferronickel from nickel oxide

Laterites and other oxidized nickel ores constitute a very important part of worldwide nickel reserves. The development of nickel oxide ore smelting has drawn heavily on iron and steel metallurgy. In ferronickel production, the nickel oxide and part of the iron oxide are reduced to metal in an electric furnace to form immiscible layers of slag and metal.
