[PDF] Rotating magnetic field separation of minerals

The behaviour of particles in a rotating magnetic field can be used as a basis for a new mineral separation method, where particles are separated on the basis of their relative ability Ito rotate in a rotating magnetic field. Both particle attraction and particle rotation separations may be combined in a single separation process, to offer ...

Magnetic Methods for the Treatment of Minerals

Magnetic Methods for the Treatment of Minerals. This book treats magnetic separation from the point of view of both the engineer in the field who operates magnetic separators and the research scientist in the laboratory. It emphasizes those aspects of magnetic separation where lack of support in fundamental research is most evident.

Mineral processing

Concentration involves the separation of valuable minerals from the other raw materials received from the grinding mill. In large-scale operations this is accomplished by taking advantage of the different properties of the minerals to be separated. These properties can be colour (optical sorting), density (gravity separation), magnetic or ...
