Abstract
The separation of mixture consisting of copper and polyvinylchloride (PVC) was studied experimentally and analytically. The separator consists of a vibratory feeder equipped with two plate electrodes, and they can be inclined about two axes with respect to the horizontal plane. The principle behind the separation technique is based on the difference in Coulomb force acting on the particles. The separation tests were performed with chopped waste electric cables. The effect of electric field strength and triboelectric charging time on separation efficiency was investigated. It is shown that it is possible to obtain high purity and recovery.
