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 …

During magnetic separation, they do not experience a magnetic attraction force. That is why diamagnetic materials are also known as non-magnetic; however, this is not strictly accurate. ... comprising permanent ring or disk magnets in conjunction with mild steel discs, was first proposed in 1968. However, the rapid development of this type of ...
