摘　　要：本文对我国拜耳法工厂的溶出、沉降、分解、蒸发工序进行了简述,分析了其现状、存在问题及在技术创新方面需要开展的工作,尤其是对决定氧化铝产量与质量的分解工序作了重点阐述,指出其当前存在的问题,如分解率、产品强度、产品粒度及其周期性变化规律,并寻找出解决途径。针对目前氧化铝工业的生产状况及铝土矿资源的现状,有必要开发一种适于处理高硫、高硅、高有机物铝土矿的高效氧化铝生产新工艺,以开创氧化铝工业技术进步的新篇章。In this paper,the digestion,settlement,decomposition and evaporation processes of Bayer process in China are briefly introduced,analyzing the current situation,existing problems and the work to be carried out in technical innovation.In particular,the decomposition process determining the yield and quality of alumina is described emphatically,pointing out the existing problems,such as decomposition rate,product strength,product granularity and its periodic variation,to find out proper solutions.In view of the current production status of alumina industry and bauxite resources,it is necessary to develop a new alumina production process for the high-sulfur,high-silicon and high-organic bauxite,which can contribute to open a new chapter of technological progress in alumina industry.
