摘　　要：赤泥是氧化铝生产过程中产生的最大工业废渣,给社会、环境带来了沉重的负担。针对国内氧化铝行业用矿石高铝高硅矿和低铝低硅矿,介绍了利用选铁分砂的新工艺来对两种矿石所产拜耳法赤泥进行综合回收利用的方法。Red mud is the largest waste during alumina production, has brought the serious burden to the society and environment. In the light of the high grade bauxite with high silicon and low grade bauxite with low silicon adopted in alumina industry in China, the new iron and sand separation process is introduced in this paper, which is used for comprehensive recovery and utilization the red mud from Bayer process.
