摘　　要：研究了从某进口红土镍矿中湿法提取镍,确定了最佳工艺条件。结果表明:用硫酸在常压下浸出,镍浸出率达78.62%;用硫化钠溶液从浸出液中沉淀镍,所得硫化镍产品中镍品位达20%;最后调整沉淀母液pH,控制一定温度,副产氢氧化镁,所得氢氧化镁中氧化镁质量分数达58.40%。Hydrometallurgy of laterite-nickel ore to extract Ni was investigated.The optimum conditions were determined by tests.The leaching rate of Ni was of 78.62% at normal pressure using sulfuric acid.Ni mass fraction in the product was of 20%.MgO mass fraction was of 58.40% in the by-product.
