Abstract
The Outokumpu Oy Cobalt Plant processes nickel, copper, and zinc bearing cobaltiferrous pyrite concentrate. Main operations: sulfatizing roasting, leaching, solution purification and recovery of cobalt metal. Roasting is done in fluidized beds, most of the material being fed as calcine. Green concentrate is used only for the heat requirements, and for maintaining a proper gas atmosphere for sulfatizing. Selection of the reactor design and the processing steps was based on laboratory and pilot plant studies.
