Experimental Investigation of the Efficiency of the Electroflotation Recovery of a Mixture of a Poorly Soluble Cerium Group Metal Compounds from Aqueous Solutions

Resumo

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.
