Abstract

A composite sorting apparatus for separating conductive materials from non-conductive materials comprising a drum electrode, needle-shaped electrodes, and a plate-shaped electrode, wherein the plurality of needle-shaped electrodes are arranged so that the interval X in cm (in) between discharge sections of adjacent needle-shaped electrodes with respect to the distance L1 in cm (in) from the tips of discharge sections to the drum electrode meets 0<X/L1&lE;3.
