Electrostatic Separation of Minerals | Bunting - Redditch

01-06-2020 · Electrostatic separation enables the separation of a wide range of minerals and this example, separating Pyrite from Silica Sand, provides a good example of the separation process. A feed of conducting (Pyrite FeS 2 ) and non-conducting (Silica Sand SiO 2 ) powders is fed via a vibratory feeder onto an earthed, stainless-steel roll revolving at a pre-determined rate.

What is Electrostatic Separation? (with pictures)

Electrostatic seperation uses electrostatic charges to separate crushed particles of material. Generally, electrostatic charges are used to attract or repel differently charged material. When electrostatic separation uses the force of attraction to sort particles, conducting particles stick to an oppositely-charged object, such as a metal drum, thereby separating them from the

Triboelectric effect - Wikipedia

The triboelectric effect (also known as triboelectric charging) is a type of contact electrification on which certain materials become electrically charged after they are separated from a different material with which they were in contact. Rubbing the two materials with each other increases the contact between their surfaces, and hence the triboelectric effect.
