Electrostatic separation is done by initially charging the particulates or contaminants and then moving and concentrating them at the electric field boundary. Electrical separation was first demonstrated by Hohlfield in 1824 by clearing a smoked-filled jar with an electrified point.
In mineral processing: Electrostatic separation. The electrostatic method separates particles of different electrical charges and, when possible, of different sizes. When particles of different polarity are brought into an electrical field, they follow different motion trajectories and can be caught separately.
Electrostatic separation has been widely used to separate conductors and nonconductors for recycling e-waste. However, the components of e-waste are complex, which can be classified as conductors, semiconductors, and nonconductors according to their conducting properties.

ELECTROSTATIC SEPARATION is defined as "the selective sorting of solid species by means of utilizing forces acting on charged or polarized bodies in an electric field.
Electrostatic separation (ES) has been used in several studies for the efficient fractionation of different biomasses, such as wheat bran and sunflower oil cakes, to separate cellulose, proteins, lignin and ash without water or effluent [1,25,26].
Separation of minerals utilizing differences in their electrical properties may be carried out using an electrostatic separator.It will separate electrical conductors (minerals such as cassiterite and rutile) from those that are electrical non-conductors (minerals such as zircon and siderite).
May 23, 2016· 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.
In the electrostatic separation of dissimilar materials using the electrostatic counter-current belt-type separator system, it is desirable to control certain output variables from the process in order to produce a consistent product quality.
in order to evaluate the Concluding electrostatic separation method, effect of different parameters including electrode type (point to point, plate, rod and wire type), electrode distance (3, 6 and 9 cm) and voltage and current intensity (3400V-112mA, 6800V-56mA, 10200V-38mA, 13600V-28mA) on required time for glycerin separation from biodiesel was considered.
Electrostatic separation is highly successful in certain operations, particularly in rutile recovery, however it's suitability is limited due to the strict conditions of ore feed presentation to the separators.
For recovering an enriched KCl fraction from potash ores by electrostatic separation, the ore is conditioned with a reagent comprising an aliphatic amine of 8 - 22 carbon atoms and an ammonium salt of a lower aliphatic carboxylic acid, e.g., laurylamine and ammonium acetate.
