The cornerstone volume in its field. Gravity 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 impact. Gravity Concentration Technology has repeatedly proven that optimal liberation of mineral at the coarsest particle size reduces energy expenditure across the whole plant. Whether gravity separation of coarse material is used for gangue rejection or pre-concentrating mineral-bearing particles, significant economical and environmental advantages exist.
