摘　　要：本文针对菲律宾某低品位红土矿开展高压浸出试验研究,考察了用酸量、反应温度、反应时间及矿浆浓度对镍钴浸出率的影响。试验结果表明,用酸量和反应温度对镍钴浸出率影响较大,在最佳试验条件下,镍浸出率大于97%,钴浸出率大于96%。This discusses the.study on HP AL experiment of a low-grade nickel laterite from Philippine.In this experiment,the influences of acid consumption amount,reaction temperature,reaction time and pulp concentration on the.leaching rate of nickel and cobalt were investigated.The experiment result showed that acid consumption amount and reaction.temperature has larger influ-ences on the leaching rate of nickel and cobalt.Moreover,The results also showed that the leaching rates of nickel and cobalt can be respectively above 97%and 96%.
