The conductive-induction electrostatic separators can be broadly classified into two groups: a) plate-type separators and b) rotor-type or rotating electrode separators. i) Plate-Type Separators. There are two types of the plate-type separators employed commercially: the plate electrostatic separators and the screen-plate electrostatic separators.

electrical separation of titanium and other valuable heavy minerals from beach sands. This led to a marked improve­ ment in separating-machine designs for high-voltage power supplies. Consequently, a new generation of separators were created, i.e., high-tension separators. In 1965, the world's largest electrical concentration plant

These are electrodynamic separators (also known as high-tension rollers) and electrostatic separators [22], [23]. In the electrodynamic separators, different mineral particles are charged by a corona discharge. There are two electrodes in this separator: the first to create the corona discharge and the second for mineral separation. A

Electrostatic separation is done by initially charging the particulates or contaminants and then moving and concentrating them at the electric field boundary. Electrical separation was first demonstrated by Hohlfield in 1824 by clearing a smoked-filled jar with an electrified point. In 1884, Oliver Lodge attempted to collect lead fume …
