  • HydroPyro Integration in the processing of Nickel

    Final products produced are electronickel, nickel oxide or nickel briquettes Some plants produce intermediate materials (mixed sulphides or mixed hydroxides) that are refined elsewhere After Moa Bay no new plants were built until the late nineteen nineties which saw first Bulong, then Cawse and finally in 1999 Murrin Murrin was completedPROVEN PROCESSING OPTIONS The processing of nickel laterites falls into two broad categories pyrometallurgical and hydrometallurgical The pyrometallurgical route (smelting) is the oldest and most widely used process and is used to produce either ferronickel or nickel matte 4MURDOCH RESEARCH REPOSITORYDirect Nickel Ltdsuccessfully tested its DNi laterite leaching process in a 1t/d pilot plant, a section of which is pictured above The plant used feed from PT Antam’s Buli nickel mine in Indonesia, where Direct Nickel is considering building a 10,00020,000 t/y commercialscale plant (Photo courtesy ofLeaching Laterites: Two New Processes Make Progress | E

  • Beneficiation of Nickel laterites for HPAL processing

    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 thatThe processing plant will source upgraded ore directly from a proposed nickel and cobalt laterite mine at Marlborough, approximately 175km north west of Gladstone, via a dedicated ore slurry pipeline This ore supply will be supplemented with higher quality nickel laterite oreGladstone Nickel Project Department of StateNickel can be found in laterite ores, sulfide ore, in secondary resources, and nonland resources like sea nodules[6,7] However, only 40 pct of nickel scrap can be recovered as secondary sources, nonland resources require high investment and operational costs, thus, sulfides and lateritic ores are the most important nickel sources[6,8,9,10Roasting and Leaching Behavior of Nickel Laterite Ore
