    flotation of gold ore

  • Flotation of Gold and Gold-Bearing Ores ScienceDirect

    2016-1-1  A great deal of work has been reported on specific ores, but such studies rarely distinguish between the flotation of native gold and other gold minerals. Flotation of gold ores covers a broad field, and it is a rather difficult subject to generalize on. Most problems in gold ore flotation are not connected with floating metallic gold.

  • Flotation kinetics of a pyritic gold ore ScienceDirect

    2011-1-17  Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P 80 of 205 microns to 53 microns. Second order kinetics is a much better representation of semi-batch flotation. The first order flotation rate constant is independent of particle size in this range. The second order flotation rate constant is more sensitive to variation of P 80.
