Electrostatic separation of powder mixtures based on the ...

01/04/1993  Another category of electrostatic separation is triboelectric separation, which is based on the difference in the surface charge of various components of the powder mixture. This technique has been used extensively in a variety of applications such as the potash mineral salt industry and ore beneficiation including coal [10,11].
