Abstract

The electroflotation extraction of fine particles of TiO2 and Ti(OH)4 was studied. It was determined that in water solutions of electrolytes with pH = 2 – 12 electroflotation of TiO2 proceeds inefficiently: the degree of extraction is 10 – 15%. The degree of extraction is 25 – 30% in the presence of surfactants and 90 – 95% in the presence of surfactants and the coagulant Fe+5. Electroflotation of Ti(OH)4 proceeds efficiently: the degree of extraction at pH = 3 reaches 99%, the electroflotation time 5 – 10 min, and energy consumption 0.5 kW · h/m3 of solution.
