Abstract

Language:

This study investigates the copper electrodeposition process via electrorefining in an acidic sulfate medium, specifically focusing on the influence of various operating parameters on the cathode purity, surface morphology, deposition rate, current efficiency, and power consumption. The composition of the electrolyte consists of 40 g/l of cupric ions and 160 g/l of sulfuric acid. The operating parameters examined include current density (200, 300, and 400 A/m²), electrolyte temperature (35, 50, and 65 °C), electrode spacing (15, 30, and 45 mm), and electrolyte residence time (6, 4, and 2 h). To evaluate the properties of the produced cathode, comprehensive analyses using X-ray fluorescence (XRF), scanning electron microscopy (SEM), and energy-dispersive X-ray spectroscopy (EDX) were conducted. The findings demonstrate significant variations in cathode performance based on the adjustments to the operating parameters, indicating the potential for optimization in the electrorefining process to enhance copper recovery and purity levels.
