摘　　要：针对国内外钢铁冶金粉尘的化学组成和各有价元素的赋存状态,本文比较了国内外提取钢铁冶金粉尘有价元素的工艺现状,并基于热力学基本原理,着重分析了火法处理工艺的影响因素及存在的问题。在此基础上,围绕钢铁冶金粉尘协同资源化问题,提出高效利用粉尘自身所含碳素资源,采用火法富集—湿法分离提取—尾渣资源化工艺是我国冶金行业未来实现钢铁冶金粉尘全量资源化的一条有效途径。According to the chemical composition of iron and steel metallurgical dust and the occurrence state of each valuable element at home and abroad, the current process status of extracting valuable elements from iron and steel metallurgical dust at home and abroad is compared, and the influencing factors and existing problems of the pyrotechnic treatment process are analyzed based on the basic principle of thermodynamics.On this basis, focusing on the problem of synergistic resource utilization of iron and steel metallurgical dust, it is proposed that the efficient utilization of carbon resources contained in the dust itself, and the use of pyrotechnic enrichment-wet separation and extraction-recycling tailings process, is an effective way for China's metallurgical industry to realize the full resource utilization of iron and steel metallurgical dust in the future.
