What is Magnetic Separation?

Magnetic separation is a method of waste management where magnets are used to separate metal from refuse. This is most common in single and mixed streams of recycling as the materials are collected together and separated before processing. Want to Know More. Magnetic Separation systems were first used after the Second World War in scrap yards.

Magnetic Separation - an overview | ScienceDirect Topics

Magnetic separation takes advantage of the fact that magnetite is strongly magnetic (ferromagnetic), hematite is weakly magnetic (paramagnetic), and most gangue minerals are not magnetic (diamagnetic). A simple magnetic separation circuit can be seen in Figure 1.2.5 [9].A slurry passes by a magnetized drum; the magnetic material sticks to the drum, while the nonmagnetic slurry keeps flowing.

Magnetic separation of Red Sand to produce value ...

Dec 01, 2006· 2. Magnetic separation of Red Sand 2.1. Dry drum. To determine if Darling Range Red Sand could be magnetically separated, a proof of concept trial was conducted using a Reading bench top magnetic separator. Analysis of the fractions ranging from 0.1 to 0.4 T indicated that magnetic separation was possible but not as efficient as hoped.
