Electrostatic Mineral Separation
Deals with the industrial electrostatic processes used for the separation or beneficiation of finely divided matter in various forms such as mineral ores, ore tailings, pulverized coal containing clay particles, and, in the food industry, flour containing impurities. Especially timely in that the methods presented are environmentally clean and are applicable to areas where water is not available in quantity.
