目前,我国钢铁企业、化工企业每年都有大量的含铁尘、泥、渣被弃置,这一方面造成金属大量流失,每年损失的铁金属量达600多万吨;另一方面,这些废弃之物还占了大量场地,污染了环境。因此,努力将含铁尘、泥、渣加以回收利用,对于节约金属资源,治理污染,提高经济效益,都具有重要的现实意义,应该引起我们的高度重视。 At present, every year, a large amount of iron-bearing dust, mud and slag are thrown out by China’s iron and steel enterprises and chemical enterprises. On the one hand, a large amount of metal is lost and more than 6 million tons of iron are lost each year. On the other hand, Things also accounted for a large number of sites, polluting the environment. Therefore, efforts to recycle iron-bearing dust, mud and slag have important practical significance for saving metal resources, controlling pollution and improving economic efficiency, which should arouse our attention.
