Nickel processing - Extraction and refining | Britannica

Nickel processing - Nickel processing - Extraction and refining: The extraction of nickel from ore follows much the same route as copper, and indeed, in a number of cases, similar processes and equipment are used. The major differences in equipment are the use of higher-temperature refractories and the increased cooling required to accommodate the higher operating temperatures in nickel ...

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

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 ...
