Ferronickel is usually cast on conveyor machines in ingots of 25 to 35 kg weight. The specific energy consumption for processing 1 ton of dry lean nickel ore (1% Ni) is 810 kWh or 78 200 kWh per 1 ton of nickel. The use of richer ores (2.5% to 3.0% Ni) allows the decrease of specific energy consumption at least twofold (Novikov et al., 2005 ).

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.
