Jan 12, 2018 5.3 Magnetic Separation. Magnetic separations take advantage of the magnetic properties of minerals. All minerals will have one of three magnetic properties: ferromagnetic, paramagnetic, and diamagnetic. Ferromagnetic minerals (i.e., magnetite and pyrrhotite) are magnetic and are easily separated from other minerals, since they will be ...

Magnetic separation does have some potential, as coal is nonmagnetic, whereas much of the mineral matter associated with the coal is paramagnetic or even, in some cases, ferromagnetic. However, the biggest drawback to either of these technologies is the limited throughput, as the requirement to present 6 mm particles in thin layers restricts ...

The magnetite is later recovered from the coal through magnetic separation. Coal fines (particles less than 0.5 mm in size) are washed with spiral concentrators. The refined coal and discards are separated with adjustable blades located at different points in the water stream. This allows for separation of products to the required quality.
