电浮选过程中气泡行为的研究
Bubble behavior of electro-flotation
摘要
Abstract
In order to study preferably the effects of the bubble on electro-flotation, the features and characteristic equation of the bubble were discussed. At the same time, the key factors of the bubble on electro-flotation were researched deeply and the collision probability between the particle and the bubble was also established. The results show that there is an obvious influence of the electrode material on the hydrogen bubble diameters in the acidic medium, but the effects are unconspicuous in the neutral and alkaline medium. pH of the medium has greater impacts on the diameters of the hydrogen bubble and oxygen bubble. The effects of electrode diameters and current densities have less influences on the bubble diameters, but the dispersivity of parts diameters of the bubble becomes stronger. The diameters of the hydrogen bubble for the maximal bubble contents increase with the increase of the temperature, but the distribution range of diameters has no obvious changes. The diameters of the bubble decrease with the increase of current density, and the collision probability between the particle and the bubble can get the maximum as the current density attains a certain number.关键词
