摘要：A device (32) is provided for separating particles in a material (34), the particleshaving different conductivities. The device (32) comprises a feeder (36) foraccommodating the material (34), the feeder (36) defining an outlet opening (38).Charging means (40) is located within the feeder (36) and proximate the opening (38) ofthe feeder (36), the charging means (40) being arranged to directly charge the particles.The device (32) further includes a rotatable drum (42) that is located adjacent theopening (38) of the feeder (36). In use, the charging means (40) is arranged to produce acloud of similarly charged particles that leave the feeder (36) via the opening (38) andland on the drum (42) substantially as a monolayer, with conductive particles (48)subsequently losing their charge to the drum (42) and thus falling off, while the

insulative/less conductive particles (50) remain charged and thus attracted to the surfaceof the drum (42) so as to be removed further on in the rotation of the drum (42).
