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.}, keywords = {Flotation,Pyrite,Collision,Attachment,Detachment}, url = {https://ijcce.ac.ir/article_5895.html}, eprint = {https://ijcce.ac.ir/article_5895_f9fd35cab9e769a60f7b7fa2f2f4c7c9.pdf} }
