一、前言赤泥沉降性能的好坏,是氧化铝生产中的一个重大问题。它关系到工业生产能否正常进行和沉降设备容量的正确选择,因而常被作为评价铝土矿质量的一个重要指标。赤泥的沉降性能是一个十分复杂的问题。其中既牵涉到粒度的大小和粒子的表面状态,又还与溶液的成份、温度以及添加剂的性质和数量有关。因此,在探讨赤泥的沉降性能时,对这些因素,既要分别加以研究,又应综合的加以考虑。 I. Introduction Red mud settling performance is good or bad, is a major issue in the alumina production. It is related to the correct choice of industrial production and capacity of settlement equipment and is therefore often used as an important indicator of the quality of bauxite. The sedimentation performance of red mud is a very complex issue. This involves both the size of the particles and the surface state of the particles, but also the composition of the solution, the temperature and the nature and amount of additives. Therefore, when discussing the sedimentation performance of red mud, it is necessary to study these factors separately and comprehensively.
