    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 every tonne of nickel contained in ferronickel. This heat base phyrometallurgical technology is extremely energy intensive and requires an assured power source. There are three ferronickel plants owned by Antam: the FeNi I, FeNi II and FeNi III. The total capacity of the three plants is 26,000 TNi with an assumption of peak load of 42MW and using nickel ore with 2.38% content as feed. Nevertheless, for reserves conservation, the Company usually uses ore feed with content range between 1.8% and 2.0% and with peak load around 38 MW-40 MW, so the approximated total production of the three ferronickel plants is 18,000 - 20,000 TNi.
