Plate Electrostatic Separator for Tin Ore Refining

High tension electrostatic separator is designed for separation of titaniferous mineral sands, hard rock ilmenite and rutile, cassiterite, tantalite, wolframite, iron ore, plastics from metals in waste recycling system.
 
The high-tension electrostatic plate separator (HTP) is comprised of a curved, inclined, electrically grounded plate, onto which a feed mixture is introduced, and where particles will travel over and down the surface due to gravity. As shown in Figure 2, conductive particles obtain surface charge by induction when subjected to the electric field created between the static and grounded electrodes, while the non-conductive particles remain uncharged. The electrical attraction of the static electrode lifts charged conductors from the grounded plate, thus separating them from the non-conductive particles. They then discharge at a different trajectory resulting in mineral separation.

One of the earliest commercial forms of electrostatic separators utilized a sloping plate. These separators were constructed of thin sheet metal plates, either straight or curved, that were positioned in a sloping fashion to allow free flow of granular material under an active electric field. Under the influence of an electrostatic field, conductive particles, especially fine grains, were lifted towards the charged electrode, while the coarse non-conducting particles were effectively rejected. This is the converse of the separation in a high-tension roll separator, where most of the effective separation is of fine non-conductors from coarse conductors. Therefore, a combination of high tension roll separators, as primary roughers, followed by final cleaning using plate type separators is employed in many mineral sand processing flowsheets.
