    Rcovery of gold in pyritic ores Mine

    In most instances, visible gold can not be seen under microscopic examination of pyrite gold ores. However, if the ore is ground to 200 mesh, most times, a few specs of gold can be visibly seen under microscopic examination. Based upon numerous case studies, it appears that gold particles in pyrite are generally fine, ranging from 75 microns ...
