Separating Minerals by Electromagnetic - 911

2018-2-5  While chemically pure minerals possess magnetic permeability independently of any iron they may carry, in practice it is almost always the effect of a trace or more of iron, either chemically combined or present as an impurity, that is utilized for separation. In minerals which combined iron renders separable the magnetic permeability varies more or less regularly with the amount of iron combined; but minerals which depend for their separation upon the presence of iron

Processing a rare earth mineral deposit using gravity

2014-7-1  Magnetic separation of minerals is based on different behaviours of mineral particles when in an applied magnetic field. Unpaired electrons present in certain types of atoms cause magnetic dipoles which lead to the creation of magnetic moments in a material that can in turn result in a magnetic force on the material when these moments are aligned by an externally applied magnetic field.
