Abstract: | 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. |
