摘要：

Two thermodynamic models for predicting selectivity coefficients for the pairs Be2+/Cu2+, Mg2+/Cu2+, Ca2+/Cu2+, Sr2+/Cu2+, and Ba2+/Cu2+ in ion flotation with the dodecyl sulfate ion as a collector are compared. The dehydration model largely gives exaggerated results, and the cavity model gives both exaggert ated and underestimated values compared with the experimental selectivity coefficients. The cavity model was found to better describe molecules and ions of different sizes.
