在拜耳法溶出铝土矿过程中,含硫矿物全部或部分地被分解,致使铝酸盐溶液受到硫的污染。铝土矿中的硫转入溶液的程度与以下许多因素有关:硫化物和硫酸盐的矿物形态,溶出温度和时间,溶出用溶液的碱浓度,铝土矿中的其它杂质(其中包括硫)的含量,等等。文献的作者得出的结论是,铝土矿中的 During the Bayer process for the dissolution of bauxite, the sulfur-containing minerals are decomposed in whole or in part, rendering the aluminate solution contaminated with sulfur. The degree to which sulfur in the bauxite is transferred to the solution depends on a number of factors including the mineral form of sulphide and sulphate, the dissolution temperature and time, the alkali concentration of the solution used for dissolution, other impurities in bauxite, including sulfur, The content, and so on. The authors of the literature concluded that the bauxite in the
