    Recovery of Nickel and Processing of Magmatic Sulfide Ores. The processing of magmatic sulfide ores differs from laterites: sulfide ores are crushed in multiple steps to separate the ore minerals from the gangue. At each stage the ore is separated by size, using vibrating screens, as well as magnetic separation of iron-rich pyrrhotite.

    3.3.1 Nickel extraction process and nickel slag formation. Primary nickel is produced from two very different ores: sulfide ores and laterite (oxide) ores. Sulfide ores, which are generally mined from underground and often found in conjunction with copper-bearing ores, contain copper–iron sulfides in association with nickel–iron sulfides.

  • Processing of Nickel Laterite Ores on the Rise

    Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the ...

    Employ bioleaching for base metals, such as zinc, copper and nickel, or mineral bioxoidation to enhance extraction of gold and silver. Both methods rely on bacterium, such as hiobacillus ferrooxidans, to recover precious metals. For example, stack ore in piles 200 feet deep. Apply water-diluted sulfuric acid to enable bacterium to grow.

    Nickel is commonly present in two principal ore types – sulfide or laterite ores. Sulfide ores are typically derived from volcanic or hydrothermal processes and usually include copper (Cu) and/or cobalt, and sometimes other precious metals such as gold or platinum and palladium (generally grouped as platinum group metals or PGMs).

  • NICKEL AND COBALT ORES: FLOTATION

    The nickel content in such sulRde ores is generally low (0.2}3%) and varies from place to place in the same deposit. The low nickel content of the present-day nickel sulRde ores renders them unsuitable for either direct smelting or hydrometal-lurgical extraction, thus requiring beneRciation. The usual method of nickel extraction from sulRde

  • Nickel Geoscience Australia

    Most mined nickel derives from two types of ore deposits that form in very different geological environments: magmatic sulfide deposits, where the principal ore mineral is pentlandite [(Ni,Fe) 9 S 8], and laterites, where the principal ore minerals are nickeliferous limonite [(Fe,Ni)O(OH)] and garnierite (a hydrous nickel silicate). Magmatic ...

  • Copper Extraction from Sulfide Ores - Latest Contents

    This process is used for the extraction of copper from low grade sulfide ore. In this process, the crushed and ground ore in bulk (about 100,000 tons) is exposed to air and water in big tanks. The air in the presence of water gradually oxidizes copper and iron sulphides to their surphides. The process is completed in about one year.
