  • 08. Srecko Stopic - RWTH Aachen University

    lateritic ores via mining and metallurgy in different parts of the world. In this paper, several exploitation scenarios for hydrometallurgical treatment and benefication of lateritic ores will be shown: Direct Nickel Process, Ravensthorpe and Murrin Murrin in Australia and Meta Cobalt Nickel in Turkey.

  • Calcination Plant - Outotec

    CFB calciners operate in the 900 to 1,000˚C range, depending on product quality demands. The efficient heat recovery scheme leads to an overall fuel energy consumption of less than 2.8 GJ/t of alumina for the calcination process.

  • Study on the Beneficiation Process of a Nickel Oxide Ore

    For a nickel oxide ore, 1# ore sample was treated by sulfuric acid leaching and 2# ore sample was treated by ammonium sulfate roasting-sulfuric acid leaching through exploring experiments. The leaching rate of 92.04% with l# nickel oxide ore and the leaching rate of 72.36% with 2# nickel oxide ore were obtained by conducting the conditional experiments of sulfuric acid concentration, leaching ...

  • Experimental and Kinetic Study of Magnesium Extraction and ...

    Laterite-nickel ore was roasted with ammonium sulfate to extract magnesium by a single-factor experiment, and an orthogonal test was employed to optimize the conditions. The optimum roasting conditions were: calcination temperature, 450°C; calcination time, 120 min; molar ratio of reactants, 2 : 1; granularity <80 µm.

  • Nickel processing | Britannica

    The nickel content of laterites varies widely: at Le Nickel in New Caledonia, for example, the ore delivered to the smelter in 1900 contained 9 percent nickel; currently it contains 1 to 3 percent. Mining. With nickel found in two radically different types of ore, it is not surprising that the mining methods differ.

  • Study of Nickeliferrous Laterite Reduction

    Laterite is an important resource for the production of nickel. Pre-reduction of laterite is a critical step for all laterite based nickel production processes. The main kinds oflaterite, limonitic and serpentinic ore, behave differently upon reduction. Inthis study, general knowledge of laterites and nickel production were introduced. Research on

  • Lateritic nickel ore deposits - Wikipedia

    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.
