Magnetic Separation an overview | ScienceDirect Topics

Magnetic separations take advantages of natural magnetic properties between minerals in feed. The separation is between economic ore constituents, noneconomic contaminants and gangue. Magnetite and ilmenite can be separated from its nonmagnetic RFM

Influence of particle size on dry high-intensity magnetic

This can be explained that at a higher feed rate of separation, the magnetic field required to magnetize the garnet particle is sufficient at the top layer of the feed bed. The top layer of the feed bed passes through a low magnetic field gradient and in this case the garnet is of mono-density as well as magnetic susceptibility particles. So

Magnetic separation is the process of separating components of mixtures by using magnets to attract magnetic materials. The process that is used for magnetic separation detaches non-magnetic material with those who are magnetic. This technique is useful for not all, but few minerals such as ferromagnetic (materials strongly affected by magnetic fields) and paramagnetic (materials that are less

Separation Efficiency Metallurgist & Mineral Processing

The Separation Efficiency meets all the usual requirements of a true efficiency and is independent of the nature of the process used. It can be visualized as the percentage of the feed material that, in effect, actually undergoes complete separation while the rest of the feed is distributed randomly and unchanged into the two separation products.
