Since commissioning, Nui Phao's metallurgical perfor-mance of the copper and BSF roughers was below expec-tations. In March 2013, the sulphur grade in the BSF tails was 3.5% S (on average), significantly higher than the

Separation efficiency improvement of a low grade copper

The copper concentrate grades achieved from the flotation circuit at Telfer have typically fallen well short of the theoretical achievable grades despite the majority of copper being hosted in high copper bearing minerals chalcopyrite, chalcocite, bornite and others.

The result indicated that 37% of copper in the tails was recoverable by flotation. In this particular case we did not have kinetic rate data but instead recovery by size data.
