Magnetic separator can separate magnetite, limonite, hematite, manganese siderite ore, ilmenite, wolframite, manganese ore, metallurgical manganese ore, manganese oxide, iron ore, kaolin, rare earth and so on. The magnetic separation process is realized by the magnetic and mechanical force on the particles in the magnetic field.

The term is customarily applied to a hard, coarsely banded or nonbanded, and noncherty sedimentary rock of postPrecambrian age, in contrast with iron formation. The iron minerals may be oxides (limonite, hematite, magnetite), carbonate (siderite), or silie (chamosite); most ironstones containing iron oxides or chamosite are oolitic.
