The Commongoldminingprocessgravity Separationmethod Gold gravity separation method is to separate the minerals according to their relative density usually called specific gravitythe mineral particles with different densities are subject to hydrodynamic and mechanical forces in the moving medium water air and heavy liquid resulting in suitable conditions for loose layering and separation thus separating ore particles with different densities Gravity Separation And Ore Beneficiation Ispatguru Oct 12 2018 separation of the ore particle by gravity is dependent on two factors namely i settling rate of the particles and ii difference in specific gravity when compared against the medium in which they are being separated this gives differential settling rate and has been termed the concentration criteriasettling rate of a particle is dictated by stoke law and is equal to kd2gdsdf where k is a Guides For Highsulfide Gold Processing The gravity separation method is a traditional and most basic method for gold processing which is suitable not only for placer gold beneficiation but also suitable for high sulfide gold processing commonly used gravity separation equipment includes shaking table spiral chute jig centrifugal concentrator etc Three Major Processes Ofgold Ore Separationflotation And The three most commonly used processes for gold ore separation are gravity separation flotation and cyanidation among them gravity separation is a commonly used process in placer gold mines flotation is mostly used in rock gold mines and cyanidation is suitable for refractory gold ores such as oxide ore and flotation concentrate
