Tillvaratagande av värdefulla nickel- och koboltfraktioner ur floteringsanrikningskoncentrat ur sulfidmalm med hjälp av kloridbaserad oxidativ tryckurlakning i svavelsyra |
摘要 |
<p>A hydrometallurgical process for the recovery of nickel and cobalt values from a sulfidic flotation concentrate. The process involves forming a slurry of the sulfidic flotation concentrate in an acid solution, and subjecting the slurried flotation concentrate to a chlorine leach at atmospheric pressure followed by an oxidative pressure leach. After liquid-solids separation and purification of the concentrate resulting in the removal of copper and cobalt, the nickel-containing solution is directly treated by electrowinning to recover nickel cathode therefrom.</p> |
