  • Optimisation of gold recovery by selective gold flotation …

    Copper sulphides are selectively floated from pyrite ores at high pH''s in excess of 11. It is less clear how the free gold behaves under these conditions. In addition, for extra gold recovery, further collectors are added, such as the monothiophosphates, which are known to be selective gold collectors.

  • Copper Flotation

     · Porphyry copper ores, usually medium to medium hard, require grinding to about 65-mesh to economically liberate the copper minerals from the gangue. Although a clean rougher tailing can often be achieved at 65-mesh the copper mineral is not liberated sufficiently to make a high grade copper concentrate, thus some form of regrinding is necessary on the rougher flotation copper concentrate.

  • Applications | Solvay

    Gold-Copper Ores In ores where Au has greater value than Cu, AEROPHINE Ⓡ promoters enable flotation at lower pH than xanthates, reducing lime usage and thus improving Au recovery. Having greater stability than xanthates allows them to be used under harsher low pH conditions where xanthates decompose to produce toxic H2S gas.
