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
