The focus of this thesis was to better understand the influence of grinding media on flotation of gold bearing pyrite and cyanide gold leaching in the presence of sulfide minerals (pyrrhotite, arsenopyrite and pyrite). The interactions of sulfide minerals with various grinding media (forged steel, low chromium and high chromium steel and ceramic media) were investigated and the galvanic effects are explored, as well as the effect on flotation and leaching.
