Effect of impurities in the physical-chemical properties of a copper mineral leaching solution

The physical and chemical properties of a copper leaching solution were quantified and analyzed in presence of high concentrations of chlorine, aluminum and magnesium. The properties tested were the density, viscosity and dissolved oxygen. The effect of the viscosity over time of phase separation in...

description The physical and chemical properties of a copper leaching solution were quantified and analyzed in presence of high concentrations of chlorine, aluminum and magnesium. The properties tested were the density, viscosity and dissolved oxygen. The effect of the viscosity over time of phase separation in solvent extraction was also evaluated. The concentrations used of chlorine were 20, 30 and 50 g/L, aluminum 7, 15 and 23 g/L and finally the magnesium of 6, 14 and 22 g/L. The temperatures tested were 25, 35 and45 °C. The results showed that the presence of impurities produces a significant impact on the viscosity and only small changes in density. Chlorine is the impurity with less impact, followed by magnesium, and aluminum producing the greatest impact. The temperature increase reduces the impact of these elements. The presence of impurities causes a decrease in dissolved oxygen concentration. In solvent extraction, an increase in viscosity produces longer times of phase separation.

Las propiedades analizadas fueron densidad, viscosidad y oxígeno disuelto. También se evaluó el efecto de la viscosidad sobre el tiempo de separación de fases en extracción por solvente. Las concentraciones utilizadas de cloro fueron 20, 30 y 50 g/L, las de aluminio, 7, 15 y 23 g/L, y las de magnesio, de 6, 14 y 22 g/L. Las temperaturas ensayadas fueron 25, 35 y 45 °C. Los resultados obtenidos muestran que la presencia de impurezas produce un importante impacto en la viscosidad de la solución y solamente pequeños cambios en la densidad. El elemento que menos impacta en estas propiedades es el cloro, seguido del magnesio, y el que produjo mayor cambio fue el aluminio. El aumento de temperatura reduce el impacto de estos elementos. La presencia de impurezas disminuye la concentración de oxígeno disuelto. En extracción por solventes, un aumento en la viscosidad provoca tiempos más prolongados en la separación de fases.
