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 behaviour 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.

高盐浓度对煤与矿物颗粒附着上升气泡的浮选分离影响显着，但其确切机理尚不清楚。该项目采用最先进的表面敏感光谱和建模工具来研究盐离子如何影响两个气泡之间的液膜的排水和破裂，以及与浮选过程相关的气泡产生和行为。该研究将开发更好的煤炭和矿物浮选用水，以减少药剂使用和水污染对环境的影响。该项目将大大有助于煤炭和矿产行业的知识进步。
