Review article A systematic review of sustainable gold extraction …

Physical processing methods are widely applied in mineral separation. In the case of gold ores, physical separation can be employed to produce concentrates, and in the case of free-milling ores or to produce gold intermediate-enriched mineral products, by rejecting gangue material, which facilitates more effective hydrometallurgy.
