Steel slag and red mud reaction resource recycling new technology and application
The invention relates to the field of steel slag and red mud solid waste treatment, in particular to a steel slag and red mud component recycling iron and resource recycling technology and application. The technology mainly includes the following steps that red mud B is added into steel slag A, uniform mixing is conducted, a mixture C is obtained, the mixture C is heated to 1200 DEG C-1600 DEG C,a reducing agent D is added into the mixture C, and after the reducing agent D is sufficiently reacted with the mixture C, molten iron E is separated from molten slag F. The molten slag F is subjectedto subsequent treatment, then petroleum fracture ceramsite sand, cement, glass and the like are prepared. The steel slag A can be steel mill molten steel slag or steel slag smashed after cooling. Thered mud is Bayer process red mud. The main components of the reducing agent are carbon and silicon dioxide and are preferably materials such as carbonized rice husks and gangue comprising carbon andsilicon at the same time. The mass ratio of the steel slag and the red mud is 5:95-95:5. The technology is simple and is a resource modification regeneration green short-process technology, and comprehensive utilization of red mud and steel slag resources is sufficiently achieved.
本发明涉及钢渣与赤泥固体废弃物处理领域，特别是涉及一种钢渣和赤泥组分回收铁及资源再生利用的工艺及应用。本发明主要包括如下步骤：在钢渣A中加入赤泥B，混合均匀得到混合物C，将混合物C温度升至1200℃～1600℃，在混合物C中加入还原剂D，待所述还原剂D与所述混合物C充分反应后，使铁水E与熔融渣F分离。熔融渣材F经后续处理后制备石油压裂陶粒砂、水泥、玻璃等。所述钢渣A可以是钢厂熔融钢渣或者其冷却后经粉碎后的钢渣；所述赤泥是指拜耳法赤泥；所述还原剂的组分主要为碳和二氧化硅，优选为碳化稻壳、煤矸石等同时含有碳和硅的材料；所述钢渣和赤泥的质量比为5:95～95:5。本发明工艺简单，是一种资源改性再生的绿色短流程工艺，充分实现赤泥与钢渣资源的综合利用。
