Electrostatic Separation of Minerals | Bunting
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 …
