Sustainable Mining and Metallurgy

Lead-based solid waste mainly comes from zinc, lead and copper smelting process and waste lead-acid battery recycling system. It contains a large number of valuable metals and pollutes the environment. Therefore, it is particularly important to find out the source structure, output and regional distribution of lead-based solid waste. Based on the field investigation of enterprises, this paper analyzed the main smelting technologies of zinc, lead and copper and their production of lead-based solid waste. According to the output solid waste ratio of single ton refined metal and the output of refined metal, the output of lead-based solid waste was calculated. Based on the distribution of zinc, lead and copper smelting output, the regional distribution of lead-based solid waste was described. According to the content of lead-based solid waste pollution elements and the output of lead-based solid waste, the output of valuable elements was calculated, in order to provide basic support for the development research and industrial layout of lead-based solid waste disposal technology.
