O stabilizatsii aktivnykh kompleksov v dodekaedricheskikh strukturakh vody
The action of activators that include oxyethylated groups is investigated. Supplying PAV-1 surfactant before the collection agent intensifies flotation in a number of ways: by changing the physicochemical properties of the diffuse layer of coal particles (reducing the unit surface charge); by increasing the emulsification of the apolar reagent; by promoting more orderly structure of the aqueous solution, with the formation of larger bubbles at the particle surface; and by the flocculating action of both the coal and the mineral particles. Adding activators (in amounts of 0.1–1 g/t) increases the yield of flotational concentrate by 1.9–4.1%, with simultaneous decrease in the consumption of collection agent by 20–25%.
