The investigation of the floatability improvement of

Feb 01, 2002· This may be due to the high amount of AC in the flotation cell. Consequently, improvement in the flotation performance with K+AC and K+AC+CS (non-ionic surfactant) were better than that with K+AC+cationic or anionic surfactant, as observed in flotation experiments. It was shown that using reagents improved the flotation performance.
