Minerals are non-ferrous and rare metals, as well as other common minerals in nature, have a natural variation in electrical properties. The essential difference between them is a sign of divisibility in the dispersed state, which is widely used in special methods of obtaining monomineralic samples in the laboratory or industrial production of enriched concentrates. For this purpose, it is used the modern equipment of electron-ion technology, laboratory and industrial applications. The principle of operation of these devices are based on the difference in electric charge of individual mineral components and the interaction of Culon forces the charged particles of dispersed solids in an electric field. Separation efficiency is determined by the kinetics of the charging – discharging the particles are in contact with the conducting plane. However, the available reference material parameters of minerals does not give a complete picture of the possibility of their mutual separation of the above devices. There is a need for a more universal parameter that takes into account all of the particle shape of the mineral. Processes theoretical analysis of charge separation and dispersion of solids in the corona-electrostatic separators, drum advisable to be based on developments made in relation to the conditions of capture devices, sedimentation and separation of fine particles. In this article, an example of real minerals proposed new design parameters, which characterize more precisely the kinetics of exchange of particles on the grounded electrode separators.
