The SX/EW Process has its roots in analytical chemistry where it is used to separate one metallic ion from another. It was first used as a largescale process during World War II for the recovery of uranium from its ores. The key to the process is the development of organic extractants that are specific to the metal to be extracted.

Ores Sulfides. Canadian ores are sulfides containing nickel, copper, and iron. The most important nickel mineral is pentlandite, (Ni, Fe) 9 S 8, followed by pyrrhotite, usually ranging from FeS to Fe 7 S 8, in which some of the iron may be replaced by nickel. Chalcopyrite, CuFeS 2, is the dominant copper mineral in these ores, with small amounts of another copper mineral, cubanite, CuFe 2 S 3.
