High-iron red mud dealkalization resource utilization process method and application thereof
The invention belongs to the technical field of comprehensive utilization of red mud, and particularly relates to high-iron red mud dealkalization resource utilization, a process method and application thereof. Specifically, after the high-iron red mud is subjected to the processes of ball pressing treatment, drying and temperature raising, multi-stage dealkalization and the like, metal elements such as iron and alkali in the red mud are fully recycled, meanwhile, the red mud is converted into harmless tailings, and the harmless tailings can be further applied to the fields of buildings, paving materials and the like; and meanwhile, rare metals and the like are obtained through further smelting. The process method provided by the invention is low in investment, low in operation cost, high in benefit and environment-friendly, lays a foundation for realizing harmless comprehensive utilization of the red mud, and has good practical application, especially large-scale industrialization and industrial application values.
本发明属于赤泥综合利用技术领域，具体涉及一种高铁赤泥脱碱资源化利用、工艺方法及其应用。具体的，本发明通过将高铁赤泥经压球处理、烘干提温、多级脱碱等工艺后，从而充分回收赤泥中的铁等金属元素以及碱的同时，将赤泥转化为无害尾渣，进一步可应用于建筑及铺路材料等领域；同时进一步冶炼获得稀有金属等。本发明提供的工艺方法投资少、运行成本低，收益高，同时绿色环保，为实现赤泥无害化综合利用奠定了基础，因此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。
