Optimisation of gold recovery by selective gold flotation

Gold flotation is often overlooked as a processing option as the precious metal is viewed as being associated with the sulphide particles present in the ore, even when a proportion of the gold is free. Gold does float readily, however, and the free gold can be selectively floated

Limits of the CIL circuit in copper–gold plants

Jan 01,  · 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 ( ) 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 strategies that
