Laterite Ore
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

Production increases were largely driven by Chinese domestic processing of imported laterite ore. AME forecasts RKEF to make up around 91% of the 727kt of new project production by 2030, with 545kt added in Indonesia alone. The key strengths of RKEF are high nickel recoveries of around 93%, and 100% nickel payability.
