Development Status Tendency of China's Alumina Technologies

摘要

The paper mainly introduces the technical development status of China's alumina industry: technical progress on Bayer Process applied to the processing of medium grade bauxite of diaspore, and engineering applications of large-scaled, short process flow and intensive technologies, etc.Technical problems and influence that are encountered in technical development for alumina production and the development tendency are also discussed in this paper.Development of alumina production & comprehensive utilization technologies based on high alumina content flyash is briefed in this paper.In addition, a general introduction to the development status of China's aluminum electrolysis core technologies as well as the achievement is also given in this paper.
