A High-Voltage Electrostatic Separator uses a high-voltage electric field to separate materials based on their differing electrical conductivity, effectively sorting metals from non-metals, or other conductive from non-conductive particles. It works by charging materials, often through a triboelectric effect, then using the electrostatic force in the high-voltage field to attract or repel them differently, allowing for precise separation. This equipment is crucial in industries like mining and recycling for resource recovery and impurity removal.
