KINETIC THEORY OF FLOTATION OF SMALL PARTICLES.

Abstract

In general, in the elementary flotation act, one may distinguish a stage at which the surface of the particle approaches that of the bubble and a stage involving fixation of the particle onto the bubble. A more detailed examination shows that the number of stages is greater and that the division of the process into stages is conventional. In passing over from large to small particles, the mechanism of the elementary flotation act changes qualitatively, both at the stage of approach and at the stage of fixation. Previously developed ideas have been amended and supplemented in this chapter.
