The placer/alluvial gold mining process is designed to maximize the recovery of gold and associated heavy minerals from gangue. Then, gold is separated from associated heavy minerals through a combined mining scheme of gravity, flotation, magnetic and …

Solvent extraction is a thrilling option for separation and recovery of gold from primary and secondary leaching solutions. Various solvent systems have been used worldwide …

High content of gold in near-surface oxide zones above the gold ore deposit could be recovered using cyanidation. However, restricting the use of cyanide in mines has made it difficult to recover gold within the oxide zone. In this study, we investigated an application of the reductive microwave roasting and magnetic separation (RMR-MS) process for the effective gold …
