Iron and steel smelting process will produce a large amount of flue gas,and metal-lurgical dust can be got after dedusting treatment.The dust contains carbon,calcium,iron and other valuable elements,which can be separated and recycled through resource utilization technol-ogy.Although the recovery of metallurgical dust by sintering can obtain considerable economic ben-efits,it cannot avoid the adverse effects on the control of sintering flue gas pollutants.In order to minimize the harmful effects of impurities in the dust,it is necessary to separate it from the metallur-gical dust in advance,thus,this paper focuses on the analysis and research from the angle of dust impurity separation.
