Abstract：According to the in-depth dewatering of fine flotation concentrate, a theoretical and experimental study was made to investigate the mechanism and kinetics involved in the innovative thermo-compression filtration-drying integrated process. It is pointed out that after a saturated filter cake is formed, the thermo-compression drying process can further reduce the cake moisture along with the formation and diffusion of the saturated steam dewatering surface X(t)and superheated steam dewatering surface Y(t). Through this dewatering-drying integrated process, a clear filtrate and a final dry concentrate product with a moisture content of 12. 15% can be produced. As compared with conventional thermal drying process, the energy consumption can be reduced by 59. 31%.
