China Nonferrous Metallurgy

China’s lead reserves account for less than 20% of the world’s total lead resources, about 15.8 million tons. More than 50% of the world’s lead production capacity is provided by China, About 80% of the lead is used in the battery industry. A large number of lead-based solid waste is produced in the lead production and consumption process. At the same time, the development of lithium battery technology also brings great crisis and challenge to lead smelting industry. Under the environment of over-exploitation of lead ore, insufficient guarantee life of lead resources and dependence on import of lead ore resources, it has become an urgent problem for related industries and enterprises to research and develop new lead smelting technology and lead-based solid waste treatment technology. The paper describes the technological innovation and application of lead smelting industry in China in recent years, indicating that At present, primary ore lead smelting and secondary resources smelting such as lead-based solid waste are dominated by direct bath smelting. In the future, the process of integrated continuous and high efficiency lead smelting, the recycling and utilization technology of secondary lead resources such as lead-based solid waste will become the trend. And the entirely hydrometallurgy technology of lead is expected to be further developed.
