A flotation liberation function L = k/kmax can be defined, which is a function of the fractional liberation. For this ore, the liberation function is of the form L = k/kmax = ax exp (bxc), where x is the fractional liberation (0 ⩽ x ⩽ 1), and a, b and c are constants. The liberation function is expected to depend on the ore type. The effect of contact angle on the size-by-size recovery of fully liberated chalcopyrite particles in a mechanical cell has been examined. The recovery-particle size response for these particles followed the classical shape. A plot of k/kmax vs contact angle, where kmax is the rate constant at the greatest contact angle, showed that the flotation response was essentially independent of particle size. The observed poor recovery of coarse particles cannot be attributed to lack of liberation. Partial surface liberation affects the rate constants of all particles in the same way, independently of size. The distribution of recoveries with particle size is determined by the response of fully liberated particles. The rate constants for coarse composites follow those for fully-liberated particles of the same size. The decline in recovery of coarse particles is related to the hydrodynamic conditions in the flotation cell.]]> Sat 24 Mar 2018 07:13:50 AEDT ]]> Coarse chalcopyrite recovery in a universal froth flotation machine https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:48268 Mon 13 Mar 2023 18:16:52 AEDT ]]> Liquid-assisted irregular coarse particle fluidization in a fluidized bed flotation cell: Bed of low-density versus high-density particles https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:52341 Mon 09 Oct 2023 14:58:17 AEDT ]]> Assessment of the partitioning of coarse hydrophobic particles in the product concentrate of the CoarseAIR™ flotation system using a novel mechanical cell reference method https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:50816 Fri 18 Aug 2023 11:30:12 AEST ]]>
