NOUFERROUS METALLURGICAL EQUIPMENT

Non-ferrous metal is an important material basis for national economic development, and the lead-based solid waste generated from its production process is both resource and pollutant, which can provide resources for economic development when properly disposed，and on the contrary, would cause a certain amount of pollution to the environment.This paper analyzes the source of lead-based solid waste, resource and environmental attributes, production, regional distribution, future production changes, etc.The results show that in 2022, China's non-ferrous metal smelting of lead-based solid waste production was 1152 million tons, and it is expected that the production of lead-based solid waste in 2024 will peak at 1216 million tons, and fall to 111 million tons in 2030, the lead-based solid waste is mainly located in Henan, Anhui, Yunnan, Hunan and Guangxi,which together account for nearly 60%. Combined with the technical characteristics of lead-based solid waste disposal, suggestions on lead-based solid waste and industrial layout are put forward, such as improving policies and regulations, improving the level of technology research and development and synergistic disposal.
