Magnetic separation for mining industry – Magnetense

This type of magnetic separation machine is used in wet separation processes for smaller than 1,2 mm ( – 200 mesh of 30-100 %) of fine grained red mine (hematite) limonite, manganese ore, ilmenite and some kinds of weakly magnetic minerals like quartz, feldspar, nepheline ore and kaolin in order to remove impurity iron and to purify them.

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.
