Physically sorbed collectors in froth flotation and their activity. Part II

The mechanism of the physically sorbed collector in froth flotation is under discussion in the paper. It is shown that the basic characteristics of the collecting capacity of a physically sorbed flotation agent are its solubility, surface pressure in the film of the agent at “gas-liquid” interface, and viscosity. Experimental data and practical evidence described in the paper fortify the proposed mechanism of the collecting agent under consideration. __________ Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 2, pp. 85–95, March–April, 2009.
