...%) in compared to copper (12.07 %), nickel (12.81%), cobalt (1.33%) and manganese (5.33 %). In this paper, a hydrometallurgical scheme for recovery of copper, nickel and cobalt from such an alloy is proposed. The developed scheme includes the following processes: selective dissolution of alloy in sulfuric...
