The kinetics of the electroflotation process of extracting TiO2 and TiN powders from wastewater was studied. As the experimental results show, stationary values are reached in 20 – 25 min. The electroflotation extraction ratio for titanium nitride powder without additives is low, 15 – 20%. The introduction of the anionic surfactant NaDBS and the cationic surfactant SeptaSAS increases the extraction ratio to 50 – 65% in NaCl and 45 – 60% in Na2SO4. The growth of the TiN extraction ratio is associated with the hydrophobization of the surface and growth of the particles of the dispersed phase. The highest extraction ratios are obtained by adding coagulants and coagulant-surfactant compositions. The two compositions Al3+–NaDBS and Fe3+–NaDBS work most effectively in Na2SO4 solutions; the extraction ratio is equal to 96%. High values of the extraction ratio are observed for TiO2 with the addition of the compositions Al3+ – surfactant and Fe3+ – surfactant.
