The corona electrostatic separation methods are used for sorting of metals (including non-ferrous metals) from the plastics enclosed within heterogeneous mixtures. The basic principle of the electrostatic separation is the selective sorting of a polarised or charged species under an electric field (Higashiyama and Asano, 1998).
