nickel ore resources from sulphide ore becomes rare which makes nickel laterite ore as the future of nickel extraction. Unlike sulphide nickel ore processing, laterite nickel ore processing requires higherprocessing energy through smelting.Therefore, a novel method to process laterite nickel ore using lower energy is needed.

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

Nickel laterite HPAL circuits are known for their complexity and have presented a large number of challenges to process engineers worldwide. An attitude commonly encountered by the author is that the beneficiation of the ore is relatively simple and that the difficult problems are in the realms of hydrometallurgy. On a number of occasions beneficiation has become the ''poor cousin'' in the

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/y of nickel per line. The plant could also be twinned to double the capacity to 72,000 t/y of nickel.
