摘要：

A method for measuring bubble sizes in a laboratory column cell for two- and three-phase systems is described. An increase in viscosity, solid-particle size, pulp density and air flow rate and a decrease in temperature all resulted in larger bubbles. Bubble size decreased with an increase in the frother concentration and ionic strength of the solution. An increase in pH caused an increase in bubble size but the presence of xanthate collectors had no effect on bubble size. Reasons for these observations are proposed. © 1990.
