electrostatic separation quartz

Electrostatic separation is a method of separation based on differential attraction or repulsion of charged particles under the influence of an electric field. High temperatures and low humidity favor the development of high surface charges through the mechanism of contact electrification. Original Description. just check it out. Original Title.
