MINERALIZATION OF BUBBLES DURING FLOTATION

摘要

The study is conducted for the dynamics of thinning of liquid film separating mineral particle and gas bubble at the moment of their collision in foam flotation. It is shown that for floatable and depressed minerals, the values of potentials of particles and the advancing contact angle as well as the values of potentials of bubbles and the surface tension of gas -- liquid interface can be obtained by solution of problems on thinning of liquid film and determination of meniscus shape.
