extraction of nickel from laterite ores

  • Nickel: smelting, producingMetalpedia

    Nickel is recovered through extractive metallurgy: it is extracted from its ores by conventional roasting and reduction processes that yield a metal of greater than 75% purity. In many stainless steel applications, 75% pure nickel can be used without further purification, depending on the composition of

  • Direct extraction of nickel and iron from laterite ores

    CVMR® developed the process of direct extraction of nickel and iron from laterite ores as metal carbonyls which in turn produced pure nickel and iron metals. CVMR®s carbonyl technology has been applied to several types of limonite and saprolite ores containing other metals such as copper, cobalt and PGE.

  • OPTIMIZATION OF NICKEL EXTRACTION FROM LATERITIC

    The experimental results under optimum leaching conditions, showed that the extraction of nickel from lateritic ore was 90.66%. Analysis of variance (ANOVA) was applied to experimental results. Percentage contributions of each factor for the extraction of nickel were determined.

  • EP1587964B1 Process for nickel and cobalt extraction

    A method for the recovery of nickel and cobalt from nickel and cobalt containing laterite ores, said method comprising: a) roasting feed ore in a reducing atmosphere in a rotary kiln to selectively reduce the nickel and cobalt, wherein either no, or less than 2.5% w/w reductant is added to the feed ore prior to roasting b) leaching the reduced ore with an aerated ammoniacal ammonium carbonate

  • Lateritic nickel ore deposits Wikipedia

    The typical nickel laterite mine often operates as either an open cut mine or a strip mine. Extraction. 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).

  • Optimisation of nickel extraction from laterite ores by

    Extraction of nickel from Western Australian laterite ores via sulphuric acid leaching at 250 °C has been optimised by the addition of sodium sulphate. Leaching of a nontronitic nickel laterite ore in fresh water, with a sulphuric acid loading of 420 kg/t ore extracted 93% of nickel from the ore. When limonitic nickel laterite ore was leached
