摘　　要：赤泥的沉降性能是关系到氧化铝生产过程能否顺行的重要指标之一。研究了石灰拜耳法新工艺过程中的赤泥沉降压缩性能 ,结果表明石灰拜耳法工艺过程的赤泥沉降性能略逊于常规拜耳法 ,但赤泥压缩性能良好 。Good settling properties of red mud is one of what contribute to smooth production of alumina. In this paper, the study has been conducted on the settling properties of red mud produced in Bayer Process with an excessive addition lime. The results indicated that the settling properties of red mud produced in the Bayer Process with an excessive addition lime is slightly poorer than that in conventional Bayer Process, but the former red mud with smaller ratio of L/S, and can meet the requirements of production process of alumina.
