摘要
一水硬铝石型铝土矿在拜耳法过程中很难溶出，加入石灰等添加剂可以改善其溶出性能．本文评述了石灰、其它含钙化合物、合成铁－水化石榴石以及ＣａＯ＋（Ｍｎ／Ｆｅ）等添加剂的作用效果，并对其作用机理进行了分析．
It is difficult for diasporic bauxite to digest in the Bayer process, but its digestioncharacteristics can be improved with the help of additives, e.g. CaO. The effect of additives,such as CaO, other compounds, Fe-garnet hydrate, CaO+(Mn/Fe), on the digestion of diasporicbachte in the Bayer process is reviewed and the pertinent reaction mechanism is analyzed.
