摘　　要：采用手工外磁选法,将非磁性矿物磁选后,用氯化汞-水杨酸钠乙醇溶液搅拌浸取,使金属铁和其他铁化合物进行分离,控制溶液的pH值在5.0左右,以磺基水杨酸光度法测定铁的含量.该方法的加标回收率在92.1%-104.8%之间,测定范围（质量分数）：0.012%-0.45%,满足铜磁铁矿中金属铁含量的测定要求.Making the non-magnetite separated from copper magnetite through handle-magnetic, put it in mercury （II） chloride-sulfosalicylic acid solution. To make the metallic iron separated from other iron compounds by stirring and leach-ing. To keep pH of the solution at about 5.0. Then, it to determine the metallic iron content by sulfosalicylic acid photo-metric method. The recovery of the experimental method is between 92%and 105%. The determination scope of metallic iron content in copper magnetite is from 0.012%to 0.45%in this method. It can meet the determination demand.
