Problems solved by technology

Compared with other compounds of the corresponding metals, various metal chlorides mostly have properties such as low melting point, high volatility, and easy reducibility. According to the difference in properties of chlorides, metal separation, enrichment, extraction and extraction can be effectively realized respectively. The purpose of refining, but the chlorination roasting process needs to consume expensive chlorinating agents, which limits its large-scale application and development

Description

technical field [0001] The present invention relates to the field of resource utilization of solid waste, in particular to a system for collaborative resource utilization of municipal and metallurgical refractory solid waste, or a system for resource utilization of waste incineration fly ash and iron and steel metallurgical dust. It mainly solves the environmental and social problems caused by improper disposal of waste incineration fly ash and metallurgical solid waste. Background technique [0002] With the accelerated development of urbanization in our country, the output of urban waste in our country continues to increase. At present, waste treatment mainly includes landfill, incineration and composting. Among them, incineration treatment has the advantages of volume reduction and volume reduction, and can also generate electricity. It has been widely used in recent years. However, fly ash, a by-product of waste incineration, is a dangerous waste. Because fly ash is ric...
