资源化利用是解决炼铅炉渣露天堆置占用土地资源和破坏生态环境等问题的有效手段。首先介绍了炼铅炉渣的来源及其物理化学性质,然后从有价元素的二次回收利用、制备建筑材料及制备矿山充填胶凝材料替代品等方面入手,总结了国内外炼铅炉渣资源化利用的研究现状及应用进展,分析了资源化利用较为困难的原因和存在的不足。研究表明,炼铅炉渣比其他类型炉渣的资源化利用途径少,且国内外对其资源化利用后二次污染的研究不够深入,因此,改进冶炼工艺、提高有价元素的回收率,拓宽其利用途径并形成成熟技术是炼铅炉渣大规模资源化利用的前提条件,与此同时必须进行炉渣中有害元素的固化研究,做到有害元素可防可控,从而为炼铅炉渣资源化利用和安全环保处置奠定基础。

The resource utilization of primary lead smelting slag is an effective method to solve the problem of the land occupation and destruction of the ecological environment due to the pile of primary lead smelting slag in the open air.This paper firstly introduced the origin and physical-chemical properties of primary lead smelting slag,then,it summarized the research status and application of the resource utilization of lead smelting slag at home and abroad and analyzed the difficulties and shortcomings of the utilization of lead smelting slag from the aspects of recycling elements in lead smelting slag,preparing building materials and cementitious materials for mine filling. Domestic and foreign studies show that the lead smelting slag has less ways of utilization compare to other types of slag and the research on secondary pollution after its utilization is not deep enough.Therefore,improving the smelting process to increase the recovery rate of valuable elements and widening utilization ways and forming proven techniques are prerequisites for large-scale resource utilization of lead smelting slag,meanwhile,it is necessary to carry out researches on the immobilization of harmful elements to confirm that the harmful elements in lead smelting slag can be prevented and controlled,so that the foundation can be laid for the resource utilization and safety and environmental disposal of lead smelting slag.
