The Effect of High Voltage Power Supply on Electrostatic Separation - Principles and Applications

Dear friends, recently a very innovative technology has been introduced in the mineral processing field - using high voltage power supply to improve the effect of electrostatic separation. This technology is really amazing, it can greatly increase the efficiency of mineral processing and allow us to separate minerals more precisely. Let me briefly introduce the principles and applications of this technology.

Firstly, the basic principle of electrostatic separation utilizes the different surface charges of objects to separate them under the effect of a strong electric field. The voltage of traditional electrostatic separators is relatively low, up to tens of thousands of volts at most. However, recent research has found that using higher voltage power sources can significantly improve the separation of minerals. Especially for some difficult-to-separate minerals, the separation effect is markedly improved after applying high voltage power supply.

The main benefits brought by high voltage power supply are:

First, increased electric field strength. High voltage power supply can provide over 100,000 volts or even higher voltage, which greatly increases the electric field strength and makes it easier for minerals to be separated by the electric force.

Second, improved separation precision. Under stronger electric field, the separation of different minerals is more distinct. Minerals with similar physical properties can also be effectively separated, greatly improving the precision of mineral processing.

Third, expanded application range. Many mineral types that are difficult for electrostatic separation can now be separated under high voltage power supply, broadening the application scope of electrostatic separation.

At present, high voltage power supply technology has been industrially tested and utilized in many mines, and achieved very good results. For example, in the mineral processing of copper-cobalt ore, by using 120,000 volts high voltage power supply, the recovery rate of cobalt increased by over 5%. In the mineral processing of tungsten ore, high voltage power supply improved the recovery rate of fine tungsten concentrate to over 90%.

It can be said that high voltage power supply technology has brought revolutionary progress to electrostatic separation. It tremendously improves the efficiency, precision and application scope of mineral processing, making many low-grade or difficult-to-process ores economically viable to develop. It is believed that with the continuous maturity and extensive application of this technology, high voltage power supply will further optimize the effect of electrostatic separation and continue to create new miracles!
