2.1 Introduction. The differences in magnetic susceptibility can be utilized to separate a valuable mineral from its gangue through the magnetic separation method. Similar to other materials, minerals are generally classified into three main categories, namely diamagnetic, paramagnetic, and ferromagnetic.

3.11.2.5 Magnetic Separation. Magnetic separation is a process where a contaminant is first attached onto a magnetic carrier material (e.g., magnetite), and subsequently, the contaminant-laden carrier is separated under a magnetic field. The simplest magnetic separator is a permanent magnet.
