摘要：
Kinetic trends of electroflotation extraction of sparingly soluble lanthanum compounds from solutions containing NaCl, NaNO3, Na2SO4, and Na2CO3 were established and studied. The role of surfactants of anionic, cationic and nonionogenic natures, as well as flocculants (first, of anionic and cationic type) that depend on background electrolyte composition (sulfate, chloride, carbonate, nitrate) is determined as positive. The electroflotation extraction of lanthanum hydroxide is shown to proceed with an degree of extraction of up to 96%.
