(PDF) Dry Permanent Magnetic Separator: Present
Dry permanent magnetic separators have been widely used in the mineral and coal processing industries due to their simple operation and high separation efficiency. These tools not only discardThe sorted ore is fed into the sorting space of the equipment and is primarily subjected to the combined action of magnetic and mechanical forces, with the ore grains moving in different directions to obtain magnetic and non-magnetic products due to magnetic differences caused by different magnetic forces [48], [49], [50].Developing high gradient magnetic separators for greener

Physical separation of iron ore: magnetic separation
Low-grade iron ore mined from the earth is usually composed of several minerals, desirable and undesirable. Magnetic separation means applying a magnetic field of appropriate intensity, gradient, and other conditions to separate different minerals according to their differences in magnetic susceptibility. 9.3.3.2 Limonite Ore. There are abundant limonite resources, for instance, in Yunnan province of southwest China, and the main characteristics of such magnetic ores are low density, fine dissemination or inclusion with gangues, small magnetic susceptibility, and high sensitivity to argillation during its grinding process.Magnetic Ore an overview ScienceDirect Topics

Magnetic separation using superconducting magnets
Such technology is used in rotating-drum and rotating-disk magnetic separators. Rotating-drum magnetic separators are mainly used in mines. A good example of this technology is a magnetic separator operated in one of the largest anatase TiO 2 mines in the world, located in Tapira, Minas Gerais, Brazil, used to remove ferromagnetic the end of the separator. Capacity is rather low and a 45 cm (18 in.) wide, two-magnet separator will take approximately 1.8 tonnes (2 tons) of feed per hour. Wet Magnetic Separators (i) Wet magnetic drum-type separators are used to concentrate fine, strongly magnetic materials and there are three basic types.6 Magnetic Separation Springer
