electrostatic separation application

Applications of Electrostatics | Physics. 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.

Design and Implementation of an Electrostatic …

An Electrostatic Precipitator (ESP) is a device that is used to remove and collect the particles from a flue gas by using the force of an induced electrostatic charge from a high voltage power supply unit. This is the most efficient way to solve the pollution problem as a result of wood combustion [3, 4].

How to Recover Chromium Nickel Cobalt Laterite

These laterites are soils remaining after decomposition of ultrabasic rock and contain major quantities of Co and Ni in addition to Cr. The Bureau has developed a hydrometallurgical process to recover the nickel and cobalt from laterite that includes reduction roasting, ammoniacal sulfate leaching, solvent extraction, and electrowinning.
