摘要
对云南某地蛇纹石型含镍红土矿进行了常压搅拌浸出试验研究,通过试验得出了浸出的最佳工艺条件:硫酸用量0.4kg/kg试样、矿浆浓度33.33%、温度95℃、时间120min,在此条件下,搅拌浸出2h后镍和钴的浸出率可分别达到74%和78%。
A serpentine-type nickeliferous laterite ore from Yunnan Province was subjected to atmospheric pressure agitation leaching tests. Optimum process conditions of leaching were obtained by the tests： The optimal conditions were found to be the following： the sulphuric acid consumption amounted to 0.4kg/kg ore, the slurry concentration was 33.33%, the leaching temperature was 95℃, the time was 120 minutes. The nickel and cobalt leaching recoveries achieved were up to 74% and 78%, respectively, after two hours′ching at the above conditions.
