CHAPTER8 BENEFICIATION OF IRON ORES
Low intensity magnetic separators (LIMS) are used to treat ferromagnetic and highly paramagnetic minerals such as iron and magnetite. High intensity magnetic separators (HIMS) generally have field strengths of 10 to 20 kilogauss. These separators are used to treat weakly magnetic minerals, such as hematite. Magnetic separators are commonly classified into two .
