Flotation in high salt concentration: resolving critical knowledge gaps relating the ion effect on bubble production and behavior (2014–2016)

Abstract:
Flotation separation of coal and mineral particles by attaching to rising air bubbles is significantly affected in high salt concentration but its exact mechanism still remains unclear. This project employs state-of-the-art surface sensitive spectroscopy and modeling tools to investigate how salt ions influence drainage and rupture of liquid films between two bubbles, and bubble production and behavior relevant to the flotation processes. The research will develop better water use for coal and mineral flotation to reduce reagent usage and environmental impacts of water pollution. The project will contribute significantly to knowledge advancement in the coal and mineral industry.
