Gravity separation and Ore Beneficiation – IspatGuru
Fig 1 Effect of centrifugal force on gravity force 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 criteria’Settling rate of a particle isGravity concentration is the separation of minerals based on differences in specific gravity A gravity concentration process is designed to recover very high grades of valuable ore material into very small masses The resurgence of gravity concentration in mining has come about due to its simplicity and low environmental impactGravity Concentration | Gekko
Gold Gravity Concentration Mineral Processing & Metallurgy
The object of gravity concentration is the separation of the heavy valuable mineral from the light worthless gangue Complications are often introduced by the fact that various base minerals must be separated from one another, an ore being subdivided into several products Most gold ores, however, only require separation into two parts—the “concentrates,” in which the precious metal isGravity Separation & Concentration Methods David T06:57:2304:00 To participate in the 911Metallurgist Forums, be sure to JOIN & LOGIN Use Add New Topic to ask a New Question/Discussion about Gravity Separation/ConcentrationGravity Separation & Concentration Methods
