- Separator utilizes electrical charge differences between materials, produced by surface contact known as triboelectric charging
- Material is fed into a thin gap between two parallel planar electrodes
- The materials acquire opposite charges through interparticle contact
- Charged particles are attracted to the electrode plate of opposite charge
- A high-speed open-mesh belt moves differently charged particles toward opposite ends of the separator
