摘要
铜冶炼过程产生的渣是一种含有多种有价金属的复杂固体废物,其合理有效地处理和利用一直是资源回收和环境保护领域的重要课题。随着铜资源的日益紧张及环境保护要求的提高,对铜冶炼渣进行高值化利用已成为提升铜冶炼行业可持续性的关键。本研究主要围绕铜冶炼渣中有价金属的回收技术进行探讨,包括酸浸、生物浸出、固体氧化、磁选和重力分选等。通过这些技术,不仅能够回收铜、铁、贵重金属和稀有金属,还能够有效减少环境污染,提高资源利用效率。
The slag generated during copper smelting is a complex solid waste containing multiple valuable metals,and its rational and effective treatment and utilization have always been important issues in the fields of resource recovery and environmental protection.With the increasing scarcity of copper resources and the improvement of environmental protection requirements,the high-value utilization of copper smelting slag has become the key to enhancing the sustainability of the copper smelting industry.This study mainly explores the recovery technology of valuable metals from copper smelting slag,including acid leaching,biological leaching,solid oxidation,magnetic separation,and gravity separation.Through these technologies,not only can copper,iron,precious metals,and rare metals be recovered,but environmental pollution can also be effectively reduced and resource utilization efficiency can be improved.
