Limits of the CIL circuit in copper–gold plants ...
2014-1-1 · 1. Introduction. For copper–gold ores, it is a common practice to float copper sulphide minerals and the majority of gold to a concentrate. A review of large porphyry/skarn copper–gold deposits by Zheng and Manton (2010) highlighted that average gold recovery over four years of operation was 15% lower than that of copper. This was attributed, in part, to flotation operating
