Biogenic sulphide for cyanide recycle and copper

2008-5-1  Biogenic sulphide for cyanide recycle and copper recovery4.1. Sulphide-based processes for cyanide and copper recoveryIn the SART process, the cyanide associated with the copper (and zinc, if present) cyanide complexes is released, allowing it to be recycled back to the leach process as free cyanide. Copper is also recovered as a valuable, high-grade (∼70% Cu) Cu 2 S by-product. Cyanide recycling allows the leach circuit to be operated at higher cyanide

Biogenic sulphide for cyanide recycle and copper

In the SART process (sulphidization–acidification–recycle–thickening), the cyanide associated with the copper cyanide complexes is released by NaHS dosing to precipitate copper and convert cyanide to HCN gas under weakly acidic conditions, allowing it to be recycled back to the leach process as free cyanide. Copper is also recovered as a valuable, high-grade (∼70% Cu) Cu 2 S by-product. Cyanide recycling allows the leach circuit to be operated at higher cyanide

The GlyCatTM process offers a simple and effective method to reduce cyanide consumption caused by the presence of copper in gold ores and concentrates. Reusable glycine is added to the leach to enable a 5-to-10-fold reduction in cyanide usage for the same copper feed concentration in order to yield similar gold extractions. Copper is recovered by either sulphide precipitation or resin ion ...
