Abstract Scope |
In this research, the cumulative flotation efficiency of a copper mineral containing copper carbonates, azurite, malachite and oxides such as tenorite is analyzed, using a cationic collector type dodecyl amine C12H27N (DDA) in proportions of 0.0125, 0.025, 0.05, 0.1 and 0.15 g/L and at a pH of 10, 11 and 12. The results found indicate that the optimal flotation of copper oxides is at pH 12 with a DDA ratio of 0.05 g/L, and a pulp potential - 45.6 mV With 89.2% w/w cumulative separation, higher proportions do not contribute to improving the concentration. With a less alkaline flotation pH value, for example 10.0, 83.9% w/w cumulative flotation is obtained using 0.025 g/L of DDA and a potential of +75.4 mV, in this case the increase in the collector concentration depresses the separation. The flotation products were characterized by X-ray diffraction to establish the percentage of floated phases. |
