    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 ...

    Extraction of Nickel - QS Study

    Extraction of Nickel . Main ore is Pentlandite; Nickel is extracted from ores through the Mond procedure, in which nickel oxides are purified throughout several steps into pure nickel metal. It is placed with hydrogen and carbon monoxide gases at 122 degrees Fahrenheit, which converts it to impure nickel.

    Mond process - Wikipedia

    The Mond process, sometimes known as the carbonyl process, is a technique created by Ludwig Mond in 1890, to extract and purify nickel.The process was used commercially before the end of the 19th century. This process converts nickel oxides into nickel metal with very high purity being attainable in just a single process.

    Lateritic nickel ore deposits - Wikipedia

    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). Nickel laterites are generally mined via open cut mining methods. Nickel is extracted from the ore by a variety of process routes.
