| Abstract: | A flow sheet comprised of acidic leaching, precipitating copper or iron and chromium,and N235 extracting to separate and recover nickel and cobalt from waste alloys has been proposed and tested. The results show that the purity of cobalt and nickel solutions meet thedemands of producing nickel and cobalt products. The recovery of cobalt amounts to 91.8%and that of nickel to 97.2%. |
