A maximum bubble surface loading, 0.142 was determined by fitting the model-predicted bubble velocity with available experimental data. With this maximum bubble surface loading constraint, the recovery model predicted two regimes namely a loading regime in the early flotation period and a saturated regime wherein the bubble loading capability was entirely exhausted. Simulation of a batch flotation system suggested that loss in bubble surface loading capacity occurred faster in a dense pulp compared to a dilute pulp system and the predicted recovery decreased with increasing solids concentration for the same gas volume fraction. Similar to the collision efficiency, the optimum recovery was obtained at Ti = 4%. Further, the model predicted recovery was compared to a lab scale coal flotation test and reasonable agreement was obtained.]]> Mon 20 May 2024 14:04:34 AEST ]]> Effects of turbulence on bubble-particle collision in flotation: A LeS-Lagrange approach https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:45801 Mon 07 Nov 2022 09:58:02 AEDT ]]> Numerical prediction of particle slip velocity in turbulence by CFD-DEM simulation https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:53220 Fri 17 Nov 2023 12:00:34 AEDT ]]> A review of bubble surface loading and its effect on bubble dynamics https://ogma.newcastle.edu.au/vital/access/ /manager/Repository/uon:50921 Fri 11 Aug 2023 14:50:30 AEST ]]>
