According to the difference of the specific magnetic susceptibility of various minerals, the magnetic separation machine with different magnetic field strengths is generally divided into three categories: ferromagnetic minerals; medium magnetic minerals; weak magnetic minerals. 1. ferromagnetic minerals than the susceptibility of greater than 3000 × 10-9m3 / kg · magnetic iron ore, etc. pyrrhotite, i.e. with a weak magnetic separation device can be effectively separated from gangue minerals. 2. The magnetic minerals than the susceptibility of 500 ~ 3000 × 10-9m3 / kg, such as semi martite certain titanium and iron ore, chromium ore and the like, sorted by the magnetic separator apparatus. 3. weakly magnetic minerals, than the susceptibility of 15 ~ 500 × 10-9m3 / kg, such as hematite, limonite, iron carbonate, iron manganese ore, manganese hard, rhodochrosite, rutile titanium and certain Iron ore, etc., is recovered by strong magnetic separation and other methods, and the specific magnetic susceptibility is less than 15×10-6 cm 3 /g for non-magnetic minerals such as quartz , feldspar , fluorite and the like.
