| Abstract: | Production and use of dissolved air bubbles were investigated with the purpose of improving the recovery of fine particles in ore flotation processes.The rate and extent of air dissolution were studied under different conditions of pressure, temperature, liquid volume, and gas-solid contact. The process of bubble formation by pressure release was also examined. Assessments made through dissolved oxygen measurements indicated that dissolution of air and the release of dissolved air could be achieved within a 1-minute period. Flotation tests carried out on a ?37 μm magnetite ore sample demonstrated superior results with dissolved gas bubbles compared to conventional bubbles. |
