摘要: On average, the difference in recovery between copper and gold is 15% among large scale copper/gold operations. At Telfer, a number of operating strategies have been implemented together with sequential flotation circuit design to maximise recovery. The main include targeting primary grind size optimum for recovery, designing as pyrite flotation, minimum saleable concentrate grade, allowing portion pyrite/gold recovered into leaching extract gold. These lifted both above 90%. There are opportunities further improve metallurgical performance at including single stage cleaning rougher concentrate, regrinding scavenger prior followed by additional leaching.
