Abstract
Solvent extraction studies of copper and zinc have been carried out using Versatic 10 acid, Cyanex 272 and LIX 984N separately from a model brass pickle liquor. Various parameters for the extraction and separation of copper and zinc such as effect of pH, extractant concentration, phase ratio etc. have been optimized. The results show that extraction of copper and zinc from acid free solution increased with increase in pH and their pH0.5 values were found to be 4.0 and 5.6, 3.5 and 4.6, and 2.5 and 5.5 with Versatic 10 acid, Cyanex 272 and LIX 984N, respectively. Versatic 10 acid and LIX 984N shows greater selectivity for copper compared to zinc. By McCabe Thiele diagram, number of stages required for the counter current extraction of copper and zinc has been determined for each of the solvents. The stripping study showed that 1 mol/L H2SO4 was sufficient to strip metal ions in a single contact from each of the extractant.
