Magnetic Separation - Mining Fundamentals

Magnetic separation takes advantage of the differences in magnetic properties of minerals. Most minerals fall into one of these categories: ferromagnetic, paramagnetic, and diamagnetic. Among these categories, ferromagnetic materials show the highest magnetic susceptibility, hence they can be easily separated by the magnetic separation method.
