Abstract

In this study, solvent extraction of copper from nickel in the presence of tartaric acid and sodium acetate with D2EHPA was studied. To investigate the behavior of carboxylates, parameters such as pH, carboxylate concentration and time were varied. According to the results, with the addition of 0.04 and 0.03 g/L of tartaric acid, and sodium acetate, pH of 5.12, and time of 10 min, 90% and 20% copper and nickel were extracted, respectively. At this condition, the separation factor reached a maximum value of 25.75. Therefore, the mixture of tartaric acid and sodium acetate resulted in the selective extraction of copper.
