2020-9-8 Separation process of iron ore . At present, there are about 300 kinds of iron-bearing minerals found in nature. According to their chemical composition, iron ore can be divided into magnetite, hematite, limonite and siderite; The specific magnetic susceptibility of the material is different, and iron ore is divided into strong magnetic and

The magnetic separation process is to achieve the separation in the non-uniform magnetic field of magnetic separators according to the magnetic differences among various minerals. The maximum particle size of iron ore was over 1mm, and the minimum particle size was 0.005mm. The particle size of iron ore in quartz was 0.003~0.035 mm.
