Comprehensive treatment method and system for red mud resource utilization
The invention provides a comprehensive treatment method and system for red mud resource utilization, and belongs to the technical field of industrial waste residue resource utilization. According to the method, dried and heated red mud is directly and fully contacted with reducing gas and reacts with reducing gas; ferric oxide in the red mud is reduced into ferroferric oxide, ferroferric oxide isrecovered through magnetic separation, the remaining dry red mud can be directly processed to prepare cement or used for further separation of other metals, the technological process is simple and convenient, and the method has a good practical application value, especially large-scale industrialization value and industrialization application value.
本发明提供一种赤泥资源化利用的综合处理方法和系统，属于工业废渣资源化利用技术领域。本发明通过将烘干、加温后的赤泥直接与还原性气体充分接触并反应，将赤泥中的三氧化二铁还原为四氧化三铁，磁选回收四氧化三铁，剩余干赤泥可直接加工制备水泥或者用于其他金属的进一步分选，工艺流程较为简便，具有良好的实际应用特别是大规模工业化及产业化应用的价值。
