The electrostatic shape separator combines sizing, shape separation, and separation according to difference in electrical conductivity of particles. The chief advantage of this machine over conventional-type electrostatic separators is that it sizes the material prior to separation and produces high-grade concentrates without screen …

Flash furnace electrostatic precipitator dust (FF-ESP dust) is a recycle stream in some primary copper production facilities. This dust contains high amounts of copper. In some cases, the FF-ESP dust contains elevated levels of bismuth and arsenic, both of which cause problems during the electrorefining stages of copper production. …
