The other two commonly used ore beneficiation techniques include magnetic and electrostatic separation. Magnetic separation involves the separation of minerals based on the differences in magnetic properties. At the same time, electrostatic separation deals with mineral separation by using the differences in conductivity between different minerals.

In this contribution, we present an alternative approach to the separation of electrostatic and magnetic phase shifts using the TIE formalism. In Section 2 we describe the transport-of-intensity equation and how it is usually solved using fast Fourier Transforms (FFTs). Then we introduce a new approach for phase shift separation, based on the ...

The scientific understanding of the nature of magnetic force appears to have started early in this century with the work of Langevin, in France. He explained diamagnetism and paramagnetism in terms of orbiting electrons. Another French physicist, Pierre Weiss, followed closely with a qualitative hypothesis for ferro-magnetic behaviour. This was based on the assumption that …

Physical separation of iron ore: magnetic separation
Magnetic separation is the most efficient separation method of these technologies. Modern magnetic separators are capable of processing up to 500 t ore/h per unit at a very low operating cost (0.3–0.5 kWh power and 2 m 3 recyclable water/t feed ore). Flotation has the advantage of good selectivity, but often it has much higher operating costs ...
