Mar 06, 2017 Electrostatic separation of ores in its present form is generally known as the Huff process, from the name of Charles H. Huff, of Boston, Mass., through whose constant and persistent labors (with the invention of Clinton E. Dolbear as a basis) the successful commercial process embracing separative machinery and the various electrifying devices has been developed step by step, and the
electrostatic ore processing - aircraftengine.cz. 2021-4-19 Electrostatic separation is a class of material-processing technologies commonly used for the sorting of coarse mixtures by means of electrical forces acting on charged or polarized particles.
The STET dry electrostatic separation process offers many advantages over traditional wet processing methods, such as magnetics or flotation, including No water consumption. The elimination of water also eliminates pumping, thickening and drying, as well as any
Frederick Cottrells precipitator was successfully applied in 1907 to the collection of sulfuric acid mist and shortly thereafter proven in a number of ore processing, chemical, and cement plants. Electrostatic precipitators are satisfactory devices for removing small particles from moving gas streams at high collection efficiencies.
