Abstract: With the continuous development of social economy and the continuous improvement of the industrial system,a large amount of selecting and smelting solid waste is generated during the development and utilization of mineral resources,accounting for more than 60% of industrial solid waste generated in China.One of the ways to realize the resource utilization of bulk selecting and smelting solid waste is to develop the technology of synergistic preparation of ceramsite from selecting and smelting solid waste.It can also obtain good economic benefits while protecting the environment.The paper systematically expounds the preparation process and principle of ceramsite,and introduces the main uses of different types of ceramsite products.In addition,the technical progress of preparing different types of ceramsite from selecting and smelting solid waste is discussed.Finally,prospects and suggestions for the recycling of selecting and smelting solid waste resources are put forward from three aspects: technology development,multi-source solid waste coprocessing,and the combination of production,education,research and application.

Key words: selecting and smelting solid waste, ceramsite, unburned method, sinter process, synergistic utilization
