, Xuzhou 221116, China;3. School of Chemical and Environmental Engineering, China University of Mining and Technology (Beijing), Beijing 100083, China)Abstract:Flotation column is widely used as the separation equipment for fine mineral due to its high selectivity. However, this device may be unsuitable for the coarse particle flotation and has high handling ability. A two-stage flotation column......
