Electrostatic Separation an overview ScienceDirect

Electrostatic separation is a valuable technique for heavy mineral sand beneficiation, and the successful application of this process to separate ultrafine (<37 μm) coal particles may present an opportunity to treat the fines produced in many currently operating mineral processing circuits that account for significant rare earth losses (Higashiyama and Asano, 2007).

The second method is to induce a charge (30, 000 50, 000 volts) by what is known as high intensity field. Some particles are better con­ ductors than others, thereby losing the induced charge more readily than poor conductors.
