Ironmaking 101 – From Ore to Iron with Smelting and Direct ...

In the smelting reduction process, pelletized iron oxide ore or fine ore powders are pre-reduced in a fluidized bed or reduction shaft. The reduced iron along with coal and lime is fed to a gasifier-melter, which completes the reduction process and produces pig iron or hot metal of the same quality ...

ferronickel smelting in electric furnace or hydrometallurgical processing would be preferred routes. On the other hand, if the ore quality is not adequate, nickel pig iron production in blast furnace could be an alternative. Naturally this would depend on demand for low nickel alloys which can be produced with nickel pig iron as starting material.
