摘　　要：采用DY319新型萃取剂对高镁低钻(亦可是高镁低镍溶液或高镁低镍钴溶液)溶液进行钴镁分离,得到硫酸钴溶液,钴含量可达到100g/L以上,镁含量降低至0.002g/L,钴镁分离效果较好,含镁的萃余液中镍钴含量最低可降低0.000Xg/L,有效减少有价金属的损失。A new type of extractant DY319 was used to separate cobalt and magnesium from high magnesium and low cobalt(high magnesium and low nickel solutions or high magnesium and low nickel and cobalt mixed solutions)solutions,Obtaining cobalt sulfate solution.The concentration of cobalt can reach over 100g/L,the concentration of magnesium can be reduced to 0.002g/L.The cobalt and magnesium separation effect is well,and the nickel and cobalt content in magnesium solution can be reduced to 0.000X/L,effectively reducing the loss of valuable metals.
