    The Sherritt process is a hydrometallurgical process named for Sherritt Gordon Mines Ltd. (now Sherritt International) of Sherridon and Lynn Lake Manitoba Canada, based on the older Forward process developed by Dr. Frank Forward for the recovery of copper and nickel from those same mines. Nickel sulfide concentrates can be treated by either roasting or flash smelting to produce matte from which nickel and cobalt can be recovered hydrometallurgically, or they may be treated by an ammoniasolution press

    In the copper-nickel-iron sulfide mines of Canada, Australia, Russia, and other regions, cobalt is present in place of nickel in many minerals. Cobalt arsenides, such as smaltite, safflorite, and skutterudite, with the sulfoarsenide cobaltite and the arsenate erythrite, are mined in Morocco and on a much smaller scale in many other countries.
