Abstract:
Zinc oxide ore from Lanping contained large amount of fine slime which badly deteriorated flotation performance, and it complexly intergrowed with plenty of alkaline gangues with calcium and magnesium. In order to investigate the impact of pre-desliming on flotation, experiments of direct flotation and pre-desliming flotation were carried out in the work. Finally, a zinc recovery of 88.73% with a Zn grade of 13.93% was obtained in direct flotation test, and a higher zinc recovery of 95.25% with a Zn grade of 13.56% was achieved by pre-desliming flotation.

Abstract:
Iron ore reverse flotation has been the main concentration process applied in iron ore processing plants since the 1970s. The performance of this process has been strongly affected by the control of the previous desliming stages. The presence of ultrafine particles promotes selectivity losses in the flotation circuits, in addition to a significant increase in the consumption of chemical reagents and pumping energy. The removal of ultrafine particles promotes metal losses, the need for additional dewatering steps, difficulties in handling and stacking together with flotation waste. This study f

Abstract:
Despite the widespread use of hydrocyclone in the process of potash ore desliming, its accurate design is often difficult because the feed composition is complicated and the viscosity is high in the brine system. In this study, a numerical approach based on computational fluid dynamics (CFD) was performed to describe the flow field. The numerical simulation of flow pattern in hydrocyclones for potash ore desliming was presented. Some basic information concerning the velocity and pressure distribution is given, and the results can be used as the fundamental basis for its design.

Abstract:
In this study, the effects of ultrasound on removal of impurities from raw feldspar were investigated by testing with a newly developed flotation cell with various frequency and power intensities prior to multistage feldspar flotation. Particularly, the quality of feldspar concentrates, the volume of removed slimes and the content of impurities were taken into account to reveal the impacts. Two representative feldspar ore samples taken from the Milas-Mugla region in Turkey were separately tested for desliming and flotation by conventional and ultrasonic methods under similar conditions and the

Abstract:
Research Doctorate - Doctor of Philosophy (PhD)<br>The separation of ultrafine particles is a difficult and costly process. Low particle inertia and the viscous effects of clay – type slimes reduce the recovery of valuable particles and leads to further issues in downstream processing such as materials handling and dewatering. It is therefore common practise to implement a desliming stage, usually consisting of hydrocyclones, to remove these problematic ultrafines. With this comes an inherent loss of valuable particles. Current desliming processes also demonstrate an incomplete removal of the

Abstract The MKD5 nickel sulfide orebody at Mount Keith, Western Australia, is one of the world’s lowest-grade operating Ni mines and currently the largest Ni producer in Australia.

Most of this complexity relates to the effects of hypogene and supergene alteration of the ultramafic protore, and consequent modification of both gan
