  • Processing of Nickel Laterite Ores on the Rise

    The Move to Nickel LateritesLateritic Nickel Ore ProcessingConclusionWhile sulfide nickel ores are processed via upgrading to concentrates and then smelting, this approach is not applicable to laterite ores. A variety of approaches are available to process nickel laterite ores, with the most prevalent approaches explained below. The method(s) chosen is dependent on the composition of the unique ore source. Most laterite ore deposits are made up of both limonite (iron rich) and saprolite layers, with the thickness of each layer varying significantly across different deposits. Limonite, which a

    OverviewExtractionGenesis and types of nickel lateritesOre depositsSee also

    Nickel laterites are a very important type of nickel ore deposit. They are growing to become the most important source of nickel metal for world demand (currently second to sulfide nickel ore deposits). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes. Hydrometallurgical processes include high-pressure acid leach (HPAL) and heap leach, both of which are generally followed by solvent extraction electrowinning (SX-EW) for rec
