Flotation kinetics of a pyritic gold ore ScienceDirect

Jan 17, 2011 Flotation kinetics of a pyritic gold ore was studied with respect to particle size. Gold recovery increased by 4% with grinding from a P80 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.
