  • INVESTIGATION OF SORTING TECHNOLOGY TO REMOVE .

    The AG mill circuits have not been able to sustainably achieve the design capacity of 30,000 t/d of underground ore. Thus, a fraction of the underground ore is diverted to the conventional circuit. The conventional circuit consists of crushers, rod and ball mills and traditionally has achiever lower copper recoveries than the AG circuit.

  • Ore processing – Waihi Gold

    Ore is stockpiled (1) at the processing plant, and the process begins by feeding the ore into a hopper with a loader. The ore is conveyed, and lime is added (2) to raise the pH of the ore. Following crushing through a jaw crusher (3), the ore is fed into the semi autogenous grinding (SAG) mill (4) along with water and steel balls.
