Ore genesis

Nickel is a chalcophile element which prefers sulfides, so an ultramafic or mafic rock which has a sulfide phase in the magma may form nickel sulfides. The best nickel deposits are formed where sulfide accumulates in the base of lava tubes or volcanic flows — especially komatiite lavas.

For it is easier to recovery cooper from nickel concentrate.

A New Process for Cobalt Nickel Separation

excellent cobalt-nickel separation primary leach liquor by Cyanex 272. However, manganese extraction from the leach liquor along with cobalt could not be avoided, thus increasing the cost of the process. For sulphide ores, there is another alternative; if the ore can be concentrated by flotation, matte smelting is used instead of leaching.
