Froth flotation is widely used for separating coal and minerals from the gangue. The largest particles that can be floated in the industry are 10 times smaller than the particles that can be floated under quiescent conditions. This project aims to better understand and quantify the detachment of large particles from the bubble surface. It aims to develop innovative modelling and experimental approaches to examine the effect of particle surface characteristics and hydrodynamic conditions on coarse particle detachment and flotation. New ways to save energy by floating coarse composite particles are proposed to be developed. This research is at the forefront of flotation science and technology, and is expected to deliver significant outcomes to the mining industry.

泡沫浮选是一种广泛应用于煤和矿物分离的方法。在工业中可以漂浮的最大颗粒比在静止条件下可以漂浮的颗粒小10倍。该项目旨在更好地理解和量化大颗粒从气泡表面的分离。它旨在开发创新的建模和实验方法，以研究颗粒表面特性和水动力条件对粗颗粒分离和浮选的影响。提出了利用复合粗颗粒浮选节能的新途径。这项研究处于浮选科学和技术的前沿，预计将为采矿业带来重大成果。
