Abstract

Electroflotation was studied in the systems H2O–TiO2, H2O–Ti3N4, H2O–SiC, carbon material powders‒H2O, and some others. The degree of recovery in these systems did not exceed 10–20% for 30 min of flotation in the electrolytes NaCl and Na2SO4 over a wide pH range, which was due to the small particle size of the dispersed phase and the hydrophilic properties of the surface of the powders. Introduction of the coagulants FeCl3 and AlCl3 and compositions containing surfactants to the system intensified the flotation and increased the degree of recovery in the above systems to 90–96%. For the first time, the rate constants K for electroflotation processes were calculated for typical dependences α = f(τ). With taking into account the K values and the degrees of recovery, efficiency criteria for electroflotation processes were determined for five main groups. The results of this work are important for choosing a technology for treatment of liquid industrial waste containing titanium compounds.
