HIGmill increases gold recovery for Sunrise Dam Gold Mine

HIGmill increases gold recovery for Sunrise Dam Gold Mine

Aug 05, 2021 Aug 05, 2021 As the amount of sulphide material treated increased, gold recovery decreased in response to the refractory nature of the ore. Testwork indicated that a 6% increase in recoverable gold could be obtained by grinding the sulphide material to 80% passing 10μm and leaching the mill product combined with the flotation tails in the existing carbon-in leach (CIL) circuit

An evaluation of the physicochemical degradation of gold

An evaluation of the physicochemical degradation of gold

The long-term operating characteristics of ion-exchange resins suitable for the hydrometallurgical recovery of precious metals remain largely unknown. This study examines some physicochemical properties of two promising ion-exchange resins for gold, SR-3 and PAZ-8, when subjected to experimental conditions similar to those of a typical alkaline-chlorination gold recovery process. It is
