grind size liberation for optimum flotation recovery

Grinding for Liberation and Flotation Grinding . Why grind tailings to -53 microns, the liberation size of the magnetite, if a third of the incoming ore can be thrown away at 4000 microns or larger? Unfortunately it is much easier to implement with magnetic separators and magnetite than with a process that is more size sensitive like flotaton.

flotation of gold after grinding - fantaziepecky.cz

Gold mineral flotation normally adopts one stage grinding-flotation process, but stages grinding and flotation for ore with uneven distribution. 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.
