| Abstract: | Iron ore tailing of Tonghua is used as principal raw material in this paper. On the basis of studying the effect of thermal activation temperature on mineral composition and microstructure of iron ore tailing, further more, by means of XRD, SEM, IR ete analysis technology, the effects of thermal activation temperature, activation time and other trace additives on the mineral composition and microstructure of iron ore tailing-kaolin system are studied. Thus, the process of improving iron ore tailings activation has been obtained. This study has laid the foundation for the innocuous and massive utilization of iron ore railings. |
