摘要

Environmental impact assessment of copper metallurgical processes will soon become a compulsory activity in the future. The goal of this work is to analyses the copper metallurgical processes including pyro-metallurgy and hydrometallurgy based on the life cycle assessment method implemented in GaBi software. The evaluation indicators such as global warming potential (GWP), acidification potential (AP), photochemical ozone creation potential (POCP) and human toxic potential (HTP) are taken into account. The results show that the major environmental impact phase in pyro-metallurgy derives from beneficiation because of the largest material and energy consumption. It is also shown that copper hydrometallurgy has significantly lower environmental impact than pyro-metallurgy. Based on the evaluation results, some corresponding optimization methods are recommended to reduce environmental impact.
