how is nickel extracted from nickel ore

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 production.
