Electrostatic separator - Wikipedia

An electrostatic separator is a device for separating particles by mass in a low energy charged beam.. An example is the electrostatic precipitator used in coal-fired power plants to treat exhaust gas, removing small particles that cause air pollution.. Electrostatic separation is a process that uses electrostatic charges to separate crushed particles of material.
