To produce ferronickel, saprolite nickel ore – which contain minimum 1.8% nickel and maximum 25% iron - were first treated to become calcine through a process that crushes, dries, heats and adds certain consumables to reduce acidity, using various machines. The treated nickel ore are then fed into ANTAM’s smelters at a ratio of about 70-80 tonnes of nickel ore – depending on the grade of the nickel ore - for …

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)
