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.
