Ferronickel 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). The combined nickel yield into ferronickel is 88% to 93%.
