Gold Gravity Concentration
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 partsthe concentrates, in which the precious metal is

The specific gravity of ironbearing minerals is usually higher than the specific gravity of gangue materials. Effectiveness efficiency of the gravity separation depends largely on proper crushing and sizing of the ore so as to ensure a proper size feed to the gravity separation equipment and also removal of slime from the equipment.

Gravity Separation Principle, Uses and Applications
Gravity separation, also known as gravity concentration in mineral processing, is a technique of separating valuable minerals from gangue, based on their specific weight differences. It is applied using water, particular liquids, or even air. The process of concentrating ores using gravity separation has many advantages.
