Magnetic separation of minerals is a topic that is seldom reported in the literature for two reasons. First, separation data generally are byproducts of other projects; and second, this study requires a large amount of patience and is unusually tedious. Indeed, we suspect that most minerals probably are never investigated for this property.
Gravity separation is the separation of two or more minerals of different specific gravity by their relative movement in response to the force of gravity and one or more other forces (such as centrifugal forces, magnetic forces, buoyant forces), one of which is resistance to motion (drag force) by a viscous medium such as heavy media, water or ...

Jan 15, 2021· Magnetic separation is the process where impurities and other magnetically susceptible materials are removed from a mixture with the use of a magnet. This process takes advantage of differences in the magnetic properties of minerals, which can either be of the following: Ferromagnetic — These are magnetic minerals like magnetite and pyrrhotite.
The magnetic separator consists of a large electromagnet through which mineral mixtures can be passed on a metal trough which is divided near its exit end. Varying the strength of the magnetic field and/or slope of the separation trough is used to separate minerals. All forms of mineral separation suffer from one difficulty.
