HYDROMETALLURGICAL PROCESS FOR THE RECOVERY OF NICKEL AND COBALT BY AMMONIACAL LEACHING |
摘要 |
<p>The present is a hydrometallurgical procedure for nickel and cobalt recovery, which involves leaching with ammonia-ammonium carbonate solution of the nickel and cobalt bearing mineral material, using a tubular reactors aid mineral material is previously submitted to processes such as selective reduction, cooling, new ammonia leaching, liquid/solid separation and/or nickel and/or cobalt extraction by solvent or ion-exchange resin, allowing the recovery of all the extractable nickel and up to the 130% cobalt extraction reported by the standard ammonia-ammonium leaching. <IMAGE></p> |
