The current benchmark is one RKEF line with a high capacity kiln feeding an 80 MW furnace to process approximately 1.3 million tonnes per year of new laterite ore. It is proposed that a single RKEF line comprising one kiln producing 240 t/h of calcine feeding a 120 MW furnace could process 2 million tonnes per year of dry new ore which, for an ore grade of 2% nickel, is equivalent to 36,000 t

A typical laterite ore may contain approximately 1–1.5% Ni with 40–50% Fe existing in the form of goethite [ (FeNi)O⋅ (OH)⋅ n H 2 O]. Laterite ores contain up to 40% of free and combined moisture, which is removed in the reduction process ( Ray et al., 2014 ). Similar to copper extraction, nickel ores are first beneficiated to produce
