В настоящем исследовании рассматривается более эффективный и экологически чистый процесс извлечения меди из халькопирита с использованием недавно разработанной системы выщелачивания, содержащей гликолевую кислоту, этиленгликоль и лаурилсульфат натрия (ЛСН). Соответственно, при оптимальных условиях извлечения меди было достигнуто до 85%: 1,0М гликолевой кислоты, 20% этиленгликоля, 0,8% ЛСН и температуре 75°C. Эта гликолевая кислота действует синергически, способствуя разрушению халькопирита и стабилизируя ионы меди в растворе. ЛСН улучшает проникновение раствора за счет разрушения пассивирующего слоя серы; этиленгликоль предотвращает осаждение серы. Из полученных результатов следует, что данная система выщелачивания может быть альтернативой, более устойчивой и эффективной по сравнению с традиционными пирометаллургическими методами обработки, с возможным применением в промышленном процессе извлечения меди.

This research explores a sustainable and efficient method for extracting copper from chalcopyrite, utilizing an innovative leaching system composed of glycolic acid, ethylene glycol, and sodium lauryl sulfate (SLS). The optimal conditions identified were 1,0 M glycolic acid, 20% (v/v) ethylene glycol, 0,8% (w/v) SLS, and a temperature of 75°C, achieving up to 85% copper recovery. Glycolic acid plays a dual role, promoting the breakdown of the chalcopyrite structure and stabilizing copper ions in the solution. SLS improves the leaching efficiency by disrupting the passivating sulfur layer, allowing for better solution penetration. Additionally, ethylene glycol prevents the precipitation of sulfur, further enhancing the process. The combination of these components creates a synergistic effect that improves copper recovery while minimizing environmental impact. The findings suggest that this leaching system could serve as a sustainable and efficient alternative to the traditional pyrometallurgical methods, offering potential applications in industrial copper recovery processes.
