Integrated Leaching of Cobalt Hydroxide Intermediate and Nickel-cobalt Sulfide Intermediate
摘要
Abstract
The integrated leaching of cobalt hydroxide intermediate and nickel-cobalt sulfide intermediate was studied.The experimental results show that the recovery of manganese in cobalt hydroxide intermediate and the utilization of nickel and cobalt sulfide intermediate were 99.92%and 90.65%,respectively,at the optimum conditions including quality ratio of cobalt hydroxide intermediate and nickel-cobalt sulfide intermediate of 1/5,initial acidity of reaction of 4 mol/L,reaction temperature of 70℃,liquid-solid reaction ratio of 3:1 and reaction time of 2.5 h.The residue could be used for leaching cobalt hydroxide intermediate as reductant.The objective of integrated leaching of cobalt hydroxide intermediate and nickel-cobalt sulfide intermediate was attained without the addition of any other oxygenant or reductant.Most importantly,the integrated process leaching is simple and feasible to operate and suitable for industrial production.关键词
