One of the key features of electrostatic separation is the charging of particles. In order to separate particles, they must first be electrically charged. Charging particles can occur in a number of ways, but the STET separator uses triboelectric charging. In order to do this, minerals are fed into the separator and fall into an electrode gap ...

ElectroStatic Separation. of Minerals. Electrostatic phenomenon dates back to 600 – 700 B.C. when people noticed static electric effects (attraction of hair) when amber was rubbed with fur. Indeed, the word 'electrostatic' comes from the ancient Greek word 'electron' meaning amber. Electrostatic beneficiation of dry granular plant ...
