The physicochemical efficiency of the electroflotation process for the extraction of TiCl4 hydrolysis products from aqueous electrolyte solutions was studied. They simulate the compositions of typical industrial wastes of metallurgical and metal-working industries that contain colloid-resistant compositions of titanium tetrachloride hydrolysis products, its oxides and hydroxides. The effect of various surfactants of anionic, cationic and non-ionic nature in a wide pH range (2-12) on the efficiency of electroflotation processes of extraction, separation and concentration of dispersed titanium (IV) compounds has been studied. It has been established that the electroflotation process of the extraction of hydrolysis products of TiCl4 proceeds quite effectively with a maximum degree of extraction of 98-99% (in the acidic region at pH = 3, in alkaline at pH = 8).
