How to effectively use bauxite with low or medium grade has always been a technical bottleneck in the aluminum oxide industry of China.Recently, The special metallurgy innovation team directed by Professor ZhangTingan of NEU has developed innovation of production technique for aluminum oxide.
The technologies has passed identification of China Nonferrous Metals Industry Association, among which two technologies has reached international advanced level and broke the world-wide puzzle that red mud cannot be utilized economically.
If our country makes widespread use of this technology, the production of aluminum oxide can obtain extra economic benefits 50 billion yuan .If the exsiting Bayer Process Red Mud utilizes this technology completely, we can get significant social and economic benefits.
Presently, two technological invention brought 15 patents for Invention and 2 internatioal PCT patents.Professor ZhangTingan has established the experiment of test scale expansion with annually processing capacity of50 thousand tons in his laboratory.
