Magnetic Separation and Iron Ore Beneficiation – IspatGuru

04.10.2018 · Magnetic Separation and Iron Ore Beneficiation. Magnetic separation is an old technique for the concentration of iron ores and for the removal of tramp iron. Since 1849, a number of patents on magnetic separation have been issued in USA, and texts of some of the patents before 1910 describe a variety of magnetic separators for mineral processing.

MAGNETIC SEPARATION N. Chakravorty

"tramp" iron from ores can also be regarded as a form of low-intensity magnetic separation. The unit of measurement of magnetic flux density or magnetic induction (the number of lines of force passing through unit area of material) is the tesla. Despite the fact that the c.g.s. system is now obsolete, the unit most commonly used is the gauss (G), which is 10-4 tesla, and it would

Magnetic Separation - Mining Fundamentals

Iron ores are usually subjected to the magnetic separation process, due to the high magnetic susceptibility of iron. Magnetic separation was first applied to the separation of wolframite from cassiterite. The first magnetic separator, invented by John Prince, consisted of two pairs of electromagnets with a feed belt running over them.
