  • Lateritic Nickel Ore Deposits Ore Deposits Technology

    Ore Deposits. Typical nickel laterite ore deposits are very large tonnage, low-grade deposits located close to the surface. They are typically in the range of 20 million tonnes and upwards (this being a contained resource of 200,000 tonnes of nickel at 1%) with some examples approaching a

    Selective Reduction of Laterite Nickel Ore

    laterite ore processed is due to the difficulty of nickel laterite ore processing when compared to sulphide nickel ore processing. Nickel laterite ore needs complex treatment to extract the Ni metals causing the nickel laterite ore processing more expensive than nickel sulphide ore processing. This is because Ni content of nickel laterite ore is more difficult to upgrade.

    Direct Reduction of Limonitic Laterite Nickel Ore with

    The increasing demand for stainless steel and the scarcity of sulfide nickel ore affect the increase of laterite nickel ore processing. One of the processes that has been proven can be applied to process laterite nickel ore is direct reduction. In the direct reduction, the reduction atmosphere was adjusted by controlling the volume of CO and CO2 from carbon source materials, such as coal

    Laterite Ore an overview ScienceDirect Topics

    The laterite ore is dried and reduction roasted in multihearth roasters in an atmosphere containing hydrogen and carbon monoxide in the absence of air. Nickel and cobalt are selectively reduced to the metallic form and thus rendered amenable to ammoniacal leaching, while iron remains as insoluble oxides and silicates.

    Ores unprocessed Cargo Handbook the world's largest

    Lateritic (nickel) ore develops by long-lasting weathering of the parent rock and particularly occurs in tropical areas with a repetition of wet and dry seasons. The majority of the world’s nickel resources are contained in these laterites and account for a large proportion of the world’s nickel production.
