The development and demonstration of a practical methodology for fine particle shape characterisation in minerals processing

Author: Little, Lucy Date: 2016 Due to continually declining ore grades, increasing mineralogical complexity, and increasing metal demand, models for the design and optimisation of minerals processing operations are of critical importance. These models do not currently ... Read more
The effect of energy input on flotation kinetics

Author: Safari, Mehdi Date: 2018 SYNOPSIS Energy/power input in a flotation cell is an important parameter which, if optimised, can increase the flotation rate. The optimum energy/power input within a flotation cell is still a matter of conjecture and there is a need for a ... Read more
An electrochemical and leach study of the oxidative dissolution of chalcopyrite in ammoniacal solutions

Author: Moyo, Thandazile Date: 2016 Chalcopyrite is not only the most abundant of the copper sulphides, but also the most stable, making it recalcitrant to hydrometallurgical treatment processes especially in atmospheric leaching. Hence, pyrometallurgical processes are traditionally ... Read more
An electrochemical investigation of platinum group minerals

Author: Tadie, Margreth Date: 2015 The Bushveld complex is the largest ore body in the world hosting platinum group elements (PGEs). It is a stratified orebody with three major reefs namely, the Merensky reef, UG2 reef and the Platreef. Platinum and palladium are the most ... Read more
Performance of the vertical roller mill in a mineral processing application when coupled with internal and external classifiers

Author: Little, Warren Date: 2021 Comminution is applied in all mineral processing plants where mineral liberation is needed for separation and concentration of valuable minerals. The process is energy intensive and is predominantly carried out in tumbling mills which are ... Read more
