STUDIES ON THE FROTH CHARACTERISTICS OF COMPOSITE COLLECTORS IN NONMETALLIC MINERAL FLOTATION

摘要

The flotation results of a phosphate ore are improved by replacing the conventional collectors of fatty acids with composite collectors. The synergistic effect on the froth characteristics in systems using composite collectors has then been studied, and the concept of "mixed hemimicellae" has been proposed in the adsorption of composite collectors at the air/solution interfaces.
