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.
various electrostatic separation applications [10], [11]. Tribocharging is a surface phenomenon. Therefore, it is likely to be affected by plasma treatment processes, which are known to change the surface state of insulating materials [12-15].

Electrostatic separation is a dry processing technique used for the separation of primary as well as secondary raw materials by means of electrical forces acting on charged particles. Two main process routines can be distinguished depending on differences in raw material properties: separation of conductors from non‐conductors.
Why does such separation lead to lightning? Answer: That separation takes work, which appears as electrostatic potential energy in the separated charges. The positively charged regions of the thunderhead acquire huge positive voltages, and the negatively …

The expanding role of electrostatics as applied to minerals and related fields is covered. New and existing forms of electrostatic separation are classified into two broad groups: separation of charged particles and separation of neutral particles. The basis for each form of separation is discussed along with particle examples and results obtained.
Electrostatic separation Equipment Generally two types of equipment are used for separation. These are as follows: 1. Drum type electrostatic separation unit This equipment consists of a rotating drum made of mild steel or some other conducting material, which is earthed through its support bearings as shown below in the Figure 8.

An electrostatic separator intended for separation of liquid phase systems, made up of mixtures of liquids of various electrical permittivity. In particular, the separator is intended for separation of an oil-and-water emulsion. The electrostatic separator contains a vessel, inside which there is suspended a system of electrodes energised from an external voltage source.
A coalescer is a technological device performing coalescence.They are primarily used to separate emulsions into their components via various processes; operating in reverse to an emulsifier.. There are two types of coalescers. Mechanical coalescers use filters or baffles to make droplets coalesce while electrostatic coalescers use DC or AC electric fields (or combinations).
Another important application of electrostatics is found in air cleaners, both large and small. The electrostatic part of the process places excess (usually positive) charge on smoke, dust, pollen, and other particles in the air and then passes the air through an oppositely charged grid that attracts and retains the charged particles ()
