| Abstract: | On the basis of thermodynamic calculations, diagrams of metastable electrochemical equilibria of the system copper-potassium ethylxanthate-water, at 25°C were constructed. The equilibria equations and diagrams for the total activity of EtX?] + HEtX] + 2 (EtX)2] (equalling 10?1, 10?4 and 10?7 mol/dm3), are presented. The practical conclusions resulting from these diagrams for the flotation of native copper are discussed. |
