摘要:
铅锌冶炼行业每年产生的废渣增量大和历史堆存量大。这些废渣既是危险废弃物，同时又是一种重要的二次资源，因此铅锌冶炼渣的资源化处理受到广泛的关注。文章对我国铅锌冶炼工艺现状、铅锌废渣的产生及危害和铅锌冶炼渣的综合利用技术进展进行了详细阐述，重点介绍铅锌冶炼渣的资源化利用研究进展。
Abstract:The lead-zinc smelting industry produces a large increment of waste slag each year and a large historical stockpile. These slags are not only hazardous wastes, but also an important secondary resource. Therefore, the resource treatment of lead-zinc smelting slag has received extensive attention. The article elaborates on the current situation of lead-zinc smelting process in China, the generation and hazards of lead-zinc slag and the technological progress of comprehensive utilization of lead-zinc smelting slag. The research progress on the resource utilization of lead and zinc smelting slag is introduced especially.
