BENEFICIATION OF IRON ORES A. Das and S. Roy INTRODUCTION Magnetic Separation is one of the physical concentration processes that utilizes the differences in magnetic properties of various minerals present in the ore body. The ... electrostatic, Van Der Waals, and capillary. A magnetic separator is generally classified as low intensity if

The electrostatic field is effectively shorted through the conducting particles, which are lifted towards the charged electrode in order to decrease the energy of the system. Application Electrostatic separation is used successfully for beneficiation of wide range of minerals. Important examples are: 1. Beach sand beneficiation. 2.

Drum magnetic separators are probably the most widely used type of magnetic separation equipment. The basic design of all magnetic separators are same based upon permanent magnetic technology. High performance Drum Magnets are specially designed to per your specification to get the most effective and accurate method of metal recovery.

physical/mechanical, magnetic, or electrical. Mechanical separation may be effective down to 1mm particle size, while electrical and magnetic are most suitable below 1mm particle size. In general, all beneficiation technologies respond differently to variations in particle size. But beneficiation itself means cleaning of the particles by ...

1) The magnetic field created by the induced current in a metallic sample due to time-fluctuation of the external magnetic field of the coil wants to avoid its cause (i.e., the coil's fluctuating magnetic field). 2) Thus, the induced magnetic field in the sample and the external fluctuating magnetic field of the coil repel each other.
