     · Research Highlights 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 semibatch flotation. The first order flotation rate constant is independent of particle size in this range. The second order .
