Efficient flotation Designing the optimal bubble

Flotation is about creating the proper energy dissipation rate in the cells, to obtain optimal contact between the bubbles and the particles and extracting the minerals. We wanted to design a machine that enabled us to increase the air volume and reduce the bubble size at the same time and simultaneously optimise energy dissipation rate.

Correspondence of bubble size and frother partitioning in

Jun 14, 2014Abstract. The size of bubbles created in the flotation process is of great importance to the efficiency of the mineral separation achieved. Meanwhile, it is believed that frother transport between phases is perhaps the most important reason for the interactive nature of the phenomena occurring in the bulk and froth phases in flotation, as frother adsorbed in the surface of rising bubbles is
