    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

    The SX-EW Method. SX-EW, or the Solvent Extraction – Electrowinning approach to lateritic ore beneficiation, is a hydrometallurgical method that relies on leaching, extractants, and electrowinning to produce nickel from ore. This process is often referred to as Leach Solvent Extraction – Electrowinning for its employment of a leaching step

    Abstract. A new process is developed for metallurgical beneficiation of iron laterite nickel-containing (limonite) ores with the formation of a metallic nickel-cobalt concentrate. This process includes reducing roasting of the ores with sulfur-containing additions in the temperature range 1100-1200 C, the fragmentation of the roasting product, and the magnetic separation of
