It is clear that copper-cobalt sulfide and oxide ores require processing under distinct redox conditions: copper-cobalt oxide ore needs Co 3+ reduction for enhanced extraction, while copper-cobalt sulfide ore necessitates the oxidation of S 2−. However, varying alteration levels in sulfide deposits result in a close coexistence of sulfide and ...

A shaking table is a gravity separation device that uses a series of inclined surfaces to separate particles of different densities. The table's shaking motion allows heavier particles to settle while lighter ones are washed away. This technique is particularly effective for precious metals like gold and silver, as well as for other minerals.
