摘要
本文主要通过２８０℃高温溶出贵州铝土矿所得赤泥的物相分析结果，讨论了石灰对氧化铝溶出率、碱耗、主要矿物的溶解性能的影响，并对赤泥的一些相变规律和影响因素做了一些初步研究。
Lime is a necessary additive in the process of digestion of diaspore bauxite. Basedupon the analysis of mineralogic phase compositions of the red mud gained from high-temperature (280℃) digestion of Guizhou diaspore ban-cite, the writer discusses the effects oflime on the digesting yield of alumina,on caustic losses and main mineral dissolubility. Alsoincluded in this paper are some regularities of red mud phase conversion and their effectivefactors.
