Magnetic Separation
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.
6 Magnetic Separation
separators are usually the last stage of magnetic separation to make a final magnetic concentrate and a nonmagnetic tailing. Dry Magnetic Separators (i) Magnetic head-pulley separators are the most common types of dry unit, and can be used both for magnetic particle concentration and tramp iron removal.
