  • A History of Sherritt Fifty Years of Pressure

    The typical feed in the early years was a concentrate from the Sherritt Gordon mine at Lynn Lake. It contained approximately 10% Ni, 2% Cu and 0.5% Co, the remainder being iron, sulphur and gangue. The leach process operated initially with two countercurrent stages, which were referred to as the adjustment and final leach.

    In hydrometallurgical processes, nickel sulfide ores undergo flotation (differential flotation if Ni/Fe ratio is too low) and then smelted. After producing the nickel matte, further processing is done via the Sherritt Gordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel. Then, solvent extraction is used to separate the cobalt and nickel, with the final nickel
