Copper Flotation - Mineral Processing Metallurgy

2016-5-16  Because the copper in this type of ore usually assays only plus or minus 1% copper, the porphyry copper operations must be relatively large in order to be commercial. The flowsheet in this study illustrates a typical 3,000 ton per day operation. In general most operations of this type have two or more parallel grinding and flotation circuits.

Flotation Circuit - an overview ScienceDirect Topics

The example of flotation circuit without grinding considered the concentration of copper ore. The feed to the circuit corresponded to 6 t/h of chalcopyrite (33% of copper), 12 t/h of chalcopyrite slow (16% of copper), and 300 t/h of gangue. The superstructure considers five flotation stages. If all interconnection was allowed, there were over 3 ...

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 strategies that ...
