  • Ultra fine milling for the recovery of refractory gold

    Refractory gold ores may be defined as those which yield low recoveries of gold when treated by the conventional grinding and cyanidation process. This refractory behaviour can vary from mild to severe with gold recoveries of 85 down to less than 30 1 . In Pb–Zn ore flotation unintentional activation of sphalerite often leads to difficult separation of Pb and Zn minerals during which grinding plays a key role in unintentional activation. Therefore the aim of this study was to evaluate the surface component changes of two different mineral particles and to propose the interaction between galena and sphalerite during mixed grinding using
