What Is Electrostatic Separation?
A method of mineral separation based on the difference in the electrical conductivity of minerals and the difference in the electrostatic force acting on the minerals through an electric field. When the ore particles are in contact with the high-voltage electrode, the ore particles with high conductivity instantly get the same charge and are repelled and leave the original path. It takes a long time for the ore particles with low conductivity to obtain the same charge. For a moment, it was too late to obtain the same-sex charge, and fell in the original path.

- Explanation: In this way, according to different paths of movement, ore particles with different conductivity can be separated. This method requires ore particles to be dried and de-dusted, and the particle size does not exceed 2 mm. Mostly, it is used for the separation of mixed concentrates, such as the separation of zircon in rutile concentrate, hematite and wolframite in scheelite Pyrite in concentrate, etc. [1]
