nickel concentrate processing

  • Processing of Nickel Laterite Ores on the Rise

    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

  • Nickel: smelting, producingMetalpedia

    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 SherrittGordon process. First, copper is removed by adding hydrogen sulfide, leaving a concentrate of only cobalt and nickel.
