Metal Extraction, Brass Effluent, Metal Values, Hydrometallurgical RecoveryAbstract
Metal values including Copper (Cu), Lead (Pb) and Zinc (Zn) have been effectively recovered from brass melting slag through hydrometallurgical treatments employing acid leaching methods utilizing hydrochloric acid (HCl), nitric acid (HNO3), and sulfuric acid (H2SO4). The optimization of recovery efficiency was investigated by varying the concentrations of these acid solutions. Acidic leachants proved highly effective, particularly under elevated temperatures, with percent extraction increasing in the order of nitric, hydrochloric, and sulfuric acid. The proposed method achieved a remarkable recovery efficiency exceeding 96%. Furthermore, the recovered Copper and Zinc products meet standard specifications.
