Title Bubble generation in swirl flow during air-sparged hydrocyclone flotation
Date 1996
Description Air-sparged hydrocyclone (ASH) flotation is a new, promising technology, and, since its conception, numerous applications have been successfully tested. Nevertheless, research and development efforts have continued to improve the technology with respect to operating conditions and design considerations. Results from experimental studies on bubble generation in the ASH system are presented in this paper. Bubble size distributions generated during ASH operation were determined using a high-speed photographic technique. The influence of many factors, including surfactant concentration, water flow rate, and porous-tube pore size have been studied. Test results indicate that these process variables have a profound effect on the bubble size distribution. With an increase in surfactant concentration or water flow rate (shearfield), the bubble size distributions become narrower and shift toward smaller average bubble diameters. However, the influence of pore size is more complicated. Depending on the experimental conditions, the average bubble size was found to range from about 100 to 300 /Jin in diameter.
