摘要：

The effect of various surfactants on the physicochemical parameters (particle size and zeta potential) of the disperse phase of copper, nickel, and zinc hydroxides at concentrations of cationic, anionic, and nonionic surfactants of 2, 10, 50, and 100 mg/L at pH of 9.5-10.5 was studied. The efficiency of their electroflotation extraction into a flotation froth was determined in a laboratory electroflotation module with antiwear oxide electrodes with efficiency of higher than 95% (initial concentration 50 mg/L, in the form of flotation sludge, processing time no more than 30 min, current density 0.2 A/L).
