A systematic study for the separation of zinc from solutions containing zinc, manganese, iron, cadmium and magnesium as sulfates was developed after a batch countercurrent extraction, followed by scrubbing and stripping. In the first step, batch countercurrent experiments were carried out on a synthetic solution containing 14.60 g/L Zn(II), 6.4 g/L Mn(II), 2 g/L Mg(II), 819 mg/L Ca(II) and 60 mg/L Fe(II). The results of this step showed that at a three-stage extraction and six cycles under the conditions being O/A ratio of 1:1 and temperature of 40°C, 13.06 g/L equal to 89.50% of zinc was extracted by D2EHPA whereas only 83 mg/L of manganese was loaded by the extractant. As a result, the low extraction per mole of manganese indicated the effectiveness of the extraction process for zinc, confirming the feasibility of the proposed methodology for separating zinc from other metal ions in the studied solution. Subsequently, further optimization and analysis were conducted using atomic adsorption spectroscopy to evaluate the performance of the extraction process, leading to the determination of operational parameters suitable for large-scale implementation.
