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 ...
