My research focuses on improving the flotation performance of coarse composite particles, which are typically difficult to recover due to detachment .

The study examines how particle characteristics generated during comminution influence flotation behaviour,  comparing products from GRolls® and a rod mill. The study also considers how these coarse particles behave in different flotation environments, particularly mechanically agitated cells and the HydroFloat^TM. The aim is to understand how hydrodynamics and particle properties interact to influence attachment stability and overall performance.

A key aspect of my work is exploring strategies to improve flotation of these composites, including collector delivery approaches and the use of extenders such as diesel-based emulsions. This targets improved attachment and reduced detachment without compromising selectivity.

Overall, my research links comminution-driven particle characteristics and reagent chemistry with flotation response, with the goal of optimising coarse composite recovery while maintaining grade.
