Abstract

In this research, the effect of bubble surface area flux, Sb, and particle size on FLOTATION rate constant, k, of PYRITE (FeS2) particles was studied using bubble-particle interactions. The bubble-particle COLLISION, ATTACHMENT and DETACHMENT efficiencies were calculated under different flow regimes. The k increased with increase in the COLLISION efficiency and decrease in the DETACHMENT efficiency. Also the bubble-particle collection efficiency increased with increase in the Sb. Thus difficulty in the floating of fine particles was attributed to low efficiency of the bubble-particle COLLISION efficiency while difficulty in the floating of coarse particles was due to high efficiency of bubble-particle DETACHMENT. Maximum COLLISION, ATTACHMENT and DETACHMENT efficiencies were obtained as 81.57%, 50.60% and 51.89%, respectively.
