本文主要对高梯度强磁选矿工艺技术在氧化铝赤泥提铁工艺中的应用与研究进行了相应的介绍。重点对氧化铝赤泥在各工序中的铁含量进行了相应的分析对比,对各工序的作业重量浓度分别进行了试验调整。通过对设备技术性能参数及工艺参数进行了试验、研究,从而来提高铁精粉品味,最后提出了氧化铝赤泥再生利用的其他途径。 This article mainly introduces the application and research of high gradient magnetic separation technology in alumina red mud iron extraction process. Focus on the alumina red mud in each process of the iron content of the corresponding analysis and comparison of the operation of the weight concentration of each process were adjusted experiment. Through the technical performance parameters of the equipment and process parameters were tested and studied, so as to improve the taste of iron concentrate, and finally put forward other ways of recycling alumina red mud.
