摘要
应用一水硬铝石型铝土矿溶出动力学及一水硬铝石型铝土矿中硅钛矿物的反应行为规律对现有的间接加强化溶出技术进行了技术上的剖析。认为现有的单流法溶出技术用于处理我国的一水硬铝石型铝土矿 ,都表现有某些方面的不足。我国自行开发成功的高温双流法溶出技术是实现一水硬铝石矿间接加热强化溶出的适宜选择。高温双流法溶出技术和石灰拜耳法溶出技术相结合是我国拜耳法氧化铝生产技术的发展方向。
The indirect heating intensive digestion technology is technically analyzed with digestion kinetics of diasporic bauxite and reaction behavior of silicon and titanium minerals in diasporic bauxite.There are some shortcomings in processing Chinese diasporic bauxite by one-stream process digestion technology.The high temperature two-stream digextion technology developed by China is suitable to process diaspore with indirect heating digestion technology.The technical development direction of Chinese Bayer process of alumina procduction is the combination of high temperature two-stream digestion and lime-Bayer digestion technology.
