Electrostatic separation is used in several ways, but it is most frequently used in the mineral processing industry. An essential step in mineral processing is separating valuable minerals from non-valuable parts (gangue). This step allows for the production of the high-quality minerals needed in the creation of different products.

Electrostatic-separation utilizes the difference in electrical conductivity between the various minerals in a feed material to produce differential movement in the mineral grains, and although it is applied as a concentrating process to only a small number of minerals, it has proven to be highly successful with these.
While the primary separating force in electrostatic separation is the electrical force (Eq. 6), particles are usually also subjected to a significant secondary force, that of drag [15]. For most practical conditions particles moving in afluid can be considered to accelerate immediately to move at a constant velocity, known as the terminal velocity.
