ElectroStatic Separation of Minerals Environmental XPRT

Mineral processing categorises minerals into conductors and non-conductors (dielectric) materials. When an electrostatic field is applied they behave differently, thus enabling a separation. Conductor minerals (most sulphides) will lose the charge to an earthed surface, whilst non-conductors will retain the charge and be pinned to the earthed

In investigating the problem of separating cassiterite from an ore containing 99 per cent gangue, Hatfield 1 ingeniously developed the theory and equipment whereby the dielectric properties of the constituent minerals formed the basis for their separation. Additional information on the laboratory technique has been presented by Holman 2 and is referred to by Tickell 3 and Fairbanks. 4 The

the needles should a conducting mineral grain be encountered. A snap switch was included in the line. The principle used in the dielectric separation of mineral powders depends upon the fact that the grains will be attracted to needle-points when immersed in a liquid of lower e (dielectric constant) than the e of the mineral grain.

Application of dielectrophoresis for the separation of

Mar 01, 2010· The design of the dielectric separator has gone through many phases from precipitation-type, to isomotive, to screen-type and most recently the travelling-wave separators. Contemporary dielectric separation may be enhanced by the adjustment of the frequency, temperature or the electrical conductivity of the liquid dielectric ( Andres, 1996 ).

Dielectric properties of hard rock minerals and

Jan 31, 2020· Understanding microwave-assisted breakage and fracturing of hard rocks necessitates the characterisation of the dielectric properties of basic rock-forming minerals. In the literature, there is a significant discrepancy in the loss factors (i.e., the ability of minerals in absorbing microwave energy) of the gangue minerals due to the fact that different unsuitable and inconsistent measurement
