铁合金除尘灰及渣再利用研究

In order to promote the green transformation and sustainable development of ferroalloy industry, relevant research progresses at home and abroad are systematically reviewed for the resource utilization of dusting ash and smelting slag generated in the process of ferroalloy production. This paper summarizes the efficient treatment technology of ferroalloy dust ash from the aspects of physical treatment, chemical recycling and materialized utilization; analyzes the application potential of ferroalloy slag in the fields of building materials, metallurgical reuse and environmental remediation; and explores the economics, environmental impacts and standardization bottlenecks of the existing technologies. The results show that the technologies of briquetting, wet purification and microcrystalline glass preparation can significantly improve the utilization rate of resources, but the process optimization and large-scale application still need to break through. In the future, it is necessary to strengthen multidisciplinary cross-research, promote policy support and industrial chain synergy, in order to realize the high-value and full-quantitative utilization of ferroalloy solid waste.
