含铁尾矿二次利用新途径探讨性试验研究

Experimental investigation of a new way to reuse the iron tailings

为了合理开发利用二次含铁资源,针对自行开发的一种新型球团添加剂——含铁添加剂进行了试验研究。结果表明,该添加剂不仅能满足工业生产对球团矿质量的要求,而且对球团矿的全铁品位降低幅度有所抑制,符合高炉精料入炉的要求,更重要的是利用了二次资源。

In this paper, a new additive contained iron for pellet is described. In order to use the second resources reasonably, we use this additive to produce pellets. The experiment results show that., pellets appended this additive can both achieve the request of the pellets quality of the industry, and the TFe of pellets debased can be restrained availably, and that the pellets can accord with the request of the blast furnace fine material. Besides, to use the second resources is more reasonably.
