摘要
铁矿烧结是钢铁冶炼过程中烟气粉尘排放量最大的工序,所产生的烧结烟尘含有丰富的有价金属资源,若未得到妥善的处理,即严重污染环境、危害人类健康,又将是宝贵资源的极大浪费。本文围绕铁矿烧结烟尘特性及综合处理技术研究现状和进展,系统地总结了铁矿烧结烟尘基础物理、化学特性的研究现状,分类梳理了铁矿烧结烟尘资源回收与处置的技术研究进展,研讨了铁矿烧结烟尘综合利用的研究热点和趋势,为开发出与环境保护和企业生产需求相耦合匹配的一体化综合处理技术提供了重要参考。
Iron ore sintering is the largest smoke and dust emission processing during iron and steel smelting.The sintering dust was generated from this processing,which has abundant valuable metals.If not be properly handled,the sintering dust will not only cause serious environment pollution and become hazards to human health,but also be a great waste of valuable metals.This paper focused on the research status and progress of iron ore sintering dust characteristics and comprehensive utilization technology.The research status of the physical and chemical properties of iron ore sintering dust was systematically summarized.The recovery and disposal technical research status of iron ore sintering dust were classified.The research hotspots and trends of comprehensive utilization of iron ore sintering dust were discussed as well.This paper provides an important reference for the development of integrated processing technology coupled with environmental protection and enterprise production demand.
