Abstract Scope |
The mineral oxides Cu3(CO3)2(OH)2, Cu2(CO3)(OH)2 and CuO are important natural sources of copper associated with aluminosilicate-type host rock. To give added value these are concentrated. In this research the flotation behavior of copper oxides azurite, malachite, tenorite is analyzed using a wide range of potassium amyl xanthate XAP amounts and pH values. The results show that at higher pH the flotation of copper species decreases. Thus, at pH 5.5 and with 0.15 g/L of XAP, 89.8% w/w is obtained, at a pulp potential of + 272 mV, this value expressed in reference to the standard hydrogen electrode (SHE). While, at pH values 8.0, 9.0 and 10.0, separations of 73.2, 71.9 and 42.8% w/w respectively are obtained, the proportion of XAP necessary to achieve these recoveries decreases with increasing pH, being 0.05, 0.025 and 0. 0125. g/L of XAP respectively necessary to achieve these flotation efficiencies. |
