Abstract. Electrostatic-separation utilizes the difference in electrical conductivity between the various minerals in a feed material to produce differential movement in the mineral grains, and although it is applied as a concentrating process to only a small number of minerals, it has proven to be highly successful with these.
Used in combination, and alongside magnetic separators, the Eddy Current Separator and ElectroStatic Separator enable the recovery of a high proportion of the metallic (ferrous and non-ferrous) materials from any waste. In practice, the Eddy Current Separator is ideally suited for recovering or separating non-ferrous metals above 3mm.
