Elementary stages of the flotation process: the interaction of droplets of emulsions or sublate particles with air bubbles, chemical equilibria in the interaction of surfactants with the components of the solution to be extracted, etc., are studied with the help of theoretical concepts in the field of physical chemistry of surface phenomena. Ways of intensifying the flotation recovery of surfactants using specially selected reagents are determined. The mechanism of adsorption of dyes on adsorbents of various nature was studied with the help of theoretical concepts in the field of physical chemistry of surface phenomena. Colloid-chemical patterns of water purification from Cr (VI) compounds were studied by flotation with a carrier-highly disperse paraffin and experimental data were analyzed from the positions of the DLLO theory. The methods for obtaining zirconium-silica nanosorbents based on the kinetic characteristics of the sorption of uranium compounds of these sorbents have been optimized. Processes are optimized: flotation - selective removal of REM from aqueous solutions by transferring them to complex compounds; Extraction of extractants and fatty acids from aqueous solutions by combining flotation with flocculation, extraction, sorption (on paraffin particles), extraction of surfactants using specially selected reagents; Sorption - extraction of uranium compounds by adjusting the pH of solutions, sorbent consumption, extraction of dyes by sorption on new sorbents unmodified plant.
