Application Of Dielectrophoresis For The Separation Of

Mar 01, 2010 The design of the dielectric separator has gone through many phases from precipitation-type, to isomotive, to screen-type and most recently the travelling-wave separators. Contemporary dielectric separation may be enhanced by the adjustment of the frequency, temperature or the electrical conductivity of the liquid dielectric ( Andres, 1996 ).

Jun 01, 2020 Mineral processing categorises minerals into conductors and non-conductors (dielectric) materials. When an electrostatic field is applied they behave differently, thus enabling a separation. Conductor minerals (most sulphides) will lose the charge to an earthed surface, whilst non-conductors will retain the charge and be pinned to the earthed ...
