Gravity concentration is a general term designating processes for separating and sorting granular material by means of forces that depend on the density, size and shape of the particles. When these forces are applied to the particles the latter are caused to move, those of a given density along one path and those of a different density along another, until ultimately they are sufficiently separated to be removed from the operation of the process(Principles of Gravity Concentration – 911Metallurgist, 2020).
The gravity separation method is suitable for processing materials with large density differences, such as non-ferrous metals (gold, copper, tin, lead-zinc, platinum), ferrous metals (iron, manganese), rare metals (tungsten, thorium, zirconium, niobium, tantalum, etc.), beach sand, and coal separation(Machinery, 2023).
The common gravity concentration methods mainly include 5 types: shaker, jigging, chute, dense medium, and centrifugal beneficiation.
