Extraction of Copper at Elevated Feed Concentrations

Copper is extracted from the pregnant leach solution in Mt. Gordon’s primary SX circuit having two extraction and two strip stages and using a 23% Acorga M5640 extractant mixture. The copper concentration is reduced from 35 g/L to 10 g/L. As the raffinate is recycled to leaching, the contained copper is not lost, and the acidity of the raffinate is used in the leaching step.
