INFLUENCE OF SURFACTANTS OF DIFFERENT NATURE AND ACIDITY OF THE ENVIRONMENT ON THE FLOTATION EXTRACTION OF TITANIUM DIOXIDE FROM AQUEOUS SOLUTIONS OF ELECTROLYTES
In the article, the results of studies on the electroflotation recovery of titanium dioxide are presented, they show that the process proceeds efficiently in the pH range of 3-11, with the particle size increasing to 10-50 μm by adding coagulants (OU, Fe, Al, Cu, Zn ) and flocculants or surfactants of various nature. Under optimum conditions, the recovery rate reaches 99%, the time of electroflotation does not exceed 10 minutes, the energy consumption is 0.5 kW per 1 m3 of the aqueous solution.
