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 ...

Gold nanoparticles from plants — Science Learning Hub

Gold catalysts. At Massey University, Professor Richard Haverkamp and Dr Aaron Marshall realised that, if gold recovered from plants was kept as nanoparticles, it would be more valuable than normal gold. This is because gold nanoparticles are very active catalysts, helping along a number of chemical reactions, and gold catalysts are expensive to make.
