Abstract

Electroflotation recovery of a mixture of poorly soluble cerium group metal (Ce, La, Nd, Pr, Sm) compounds from solutions modeling industrial wastewater was investigated. The effect of the cation additives SEPTAPAV KhSV.50 and Superfloc C-494 on the electroflotation efficiency indices was determined. The effect of the pH of the solution and the concentration of the precipitant Na2CO3 on the efficiency of the electroflotation recovery of a mixture of compounds of five cerium group metals was studied to explore the feasibility of industrial electroflotation recovery of poorly soluble compounds.
