MINERAL DRESSING--PHYSICALLY SORBED COLLECTORS IN FROTH FLOTATION AND THEIR ACTIVITY. PART I

摘要

It is demonstrated that the basic factor, identifying the capability to form a flotation complex, is the availability of a reagent sorbed physically on a particle surface and promoting the thinning-down of water interlayer between a mineral particle and a bubble at final stages of their approach. The numerical evaluation of the effect of physically sorbed collector on variations in the velocity of water discharge from an interlayer, partitioning a mineral particle and a gas bubble at the moment of their meeting is given.
