For the separation of low-density coal particles from mineral matter, a channel spacing of 6 mm proved effective; however, for the separation of gangue minerals from much higher density minerals such as iron ore, the shear-induced lift needs to be even higher. In this paper, we examine the influence of two different channel widths on the continuous processing of an industrial iron ore feed in the REFLUX™ Classifier. It was found that when moving from 6.0 mm to 3.0 mm channels, the ability of the system to reject coarser gangue material and retain finer high density material across a particle size range from 0.125 to 1.0 mm was increased, resulting in a higher grade product.]]> Thu 13 Jun 2019 13:07:07 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30048 T. At a low feed solids mass flux of 1.5 t m⁻²h⁻¹, the REFLUX™ Classifier produced high-grade products at a high recovery. Overall a grade of 66.1 wt-% Fe_T with Fe recovery of 80 wt-% could be achieved in a single-stage separation. Within the 0.020–0.038 mm size fraction, grades of 68.8 wt-% Fe_T were achieved with iron recoveries of 94.7 wt-%. Excellent recoveries of up to 57.0 wt-% were achieved even for the −0.020 mm size fraction.]]> Sat 24 Mar 2018 07:31:20 AEDT ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:30304 3, with the majority in the size range from 50 to 150 µm. The overall recovery of the heavy minerals component was approximately constant at 85% for solids throughputs of 10-18.5 t/(m² h). The unrecovered heavy mineral had an average density close to that of the gangue, hence was deemed unrecoverable by gravity separation. The recovery of the denser and more liberated zirconium mineral exceeded 95%. So this work demonstrated the potential for the heavy mineral to be upgraded by a factor of 16 or more in a single stage operation.]]> Mon 23 Sep 2019 11:23:20 AEST ]]> https://nova.newcastle.edu.au/vital/access/ /manager/Repository/uon:55686 Mon 17 Jun 2024 10:18:02 AEST ]]>
