Nickel extraction

Nickel extraction

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 production

    The nickel is purified by combining carbon monoxide with impure nickel at 50 C and atmospheric pressure, or from the mixture of nickel and copper, under more complex conditions, obtaining Ni (CO)4, which is volatile. By thermal decomposition at 200 C, pure nickel is recovered at high purity

    Nickel - Extraction and Purification - Mond Process. Mond Process. Purification of nickel oxides to obtain the purest metal is performed via the Mond process, which increases the nickel concentrate to greater than 99.99% purity. This process was patented by L. Mond and has been in industrial use since before the beginning of the 20th century

    May 01, 2017 The amount of nickel co-extraction was low (3%). The scrubbing tests were carried out at an A/O ratio of unity as well. The co-extracted nickel, manganese, calcium and magnesium were contacted with a cobalt salt solution containing 20 g L − 1 of cobalt (Ritcey, 2006). The cobalt in the aqueous solution displaced nickel, manganese, calcium and

    Sulphuric acid leaching has been used in the treatment of lateritic ores for the recovery of nickel and cobalt therefrom. However, in order to obtain good extraction from these ores, prolonged treatment using acid of high strength and also using high pressures and recycling steps have been necessary. In the improved method of the invention nickel and cobalt is solubilized from high-magnesia
