The nickel and cobalt are separately reduced to metal products. The flow-sheet below shows the unit operations used in the process. Source: Acid Leach Process-METMOC; Nickel-Process; The main source of the world's nickel is from copper-nickel sulphide ores with those mined at Sudbury, Ontario being by far the most extensive.

Various processes are used to treat nickel matte. One process is the ammonia pressure leach, in which nickel is recovered from solution using hydrogen reduction, and the sulfur is recovered as ammonium sulfate for use as fertilizer.In another, the matte may be roasted to produce high-grade nickel oxides; these are subjected to a pressure leach, and the solution is electro- and carbonyl refined.

A new source, New Caledonia in the South Pacific, came into production about 1877 and dominated until the development of the copper-nickel ores of the Copper Cliff–Sudbury, Ontario, region in Canada, which after 1905 became the world's largest source of nickel. By the late 1970s, production in Soviet Russia had exceeded that in Canada.
