摘　　要：实验采用自制的Hallimond管,考察了浮选时间、电流强度及矿浆浓度对气泡大小及分布的影响。试验结果表明:浮选管中的气泡数量随着浮选时间的增加而逐渐增多;气泡量随着电流强度的增加而增多,且气泡分布也变得更为均匀,平均尺寸减小;浮选过程中,产生的气泡簇的尺寸随着矿浆浓度的增大而增大。The effect of flotation retention time, current intensity and pulp density on bubble size and distribution was investigated by using self-made Hallimond tube. Results show that the number of bubbles in the flotation tube increases with the increase of flotation time. The amount of bubbles increases with the increase of current intensity, and the bubble distribution becomes more uniform and the average size decreases. In addition, it is observed that the clusters size increases as the solids concentration increases.
