Traditionally, nickel has been processed from sulfide ores in an approach similar to copper processing, in which the ore is upgraded to concentrates and then smelted. As sulfide ore resources dwindle, however, processing of lateritic nickel ores is becoming of greater necessity, with many recognizing nickel laterite ores as the future of the nickel industry.

There have been very few mining projects extracting laterite ores, and these examples have had major technical and financial difficulties that took several years to resolve satisfactorily (e.g. Moa Bay in Cuba or Greenvale-Yabulu in Australia).
