The significance of research of the low intensity magnetic separator in silicon reducing and iron increasing of magnetite is expounded. It points out that the low intensity magnetic separator can reach the goal of silicon reducing and iron increasing and the magnetic separation process is one of the methods to be chosen first. It analyzes the causes of low separation accuracy of the conventional magnetic separators used in silicon reducing and iron increasing. The current situation of research and application of the low intensity magnetic separator in silicon reducing and iron increasing are presented. The production practice shows that the magnetic agglomeration gravity separator and the magnetic column have obvious effects in silicon reducing and iron increasing of the magnetite.
