Ion Flotation of Cations of Cerium Group

摘要

The results of experimental investigation of ion flotation in solution of cerium, samarium, and europium nitrates as well as of sodium dodecyl sulfate, which was used as flotation reagent, were reported. The dependences of the distribution coefficients of rare earth ions in the ion flotation on pH of an equilibrium aqueous phase were obtained. Comparison of an extraction pH with a pH of hydrate formation allows making a conclusion on the flotation form of cerium, samarium, and europium cations.
