Future of Rotary Kiln Electric Furnaces (RKEF

The result is a smelter utilising one kiln and one furnace which treats 240 t/h of calcine and produces 36,000 t/y of Ni contained in ferronickel from ore containing 2 % Ni. Such a plant, with the minimum number of large operating units, would achieve minimum capital and operating costs per tonne of ferronickel production.
