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.
