Grinding fineness of gold For the gold wrapped in sulfide minerals, sulfide ore reaches monomer dissociation; but for the gold with gangue, grinding fineness should reach gold monomer dissociation.

Gold - CONCENTRATION OF MINERALS

Fine gold with splice recoveries by flotation too. Fine gold in intergrowths with sulfides floats well, fine golden splice with nesulfidami floats much worse. Fine golden splice is well dissolved in the leaching. Microgold is finely divided (less than 1 micron). When grinding ore microgold opens slightly, the bulk of gold remains in the mineral.
