YU Chuan-min

Abstract

Based on the analysis of the characteristics of Chinese bauxite,summarizing of previous bauxite beneficiation tests and the bauxite beneficiation results of commercial scale in 1999 and compared the techno-economic indexes of Beneficiation-Bayer Process and raw bauxite Combination Process,Bauxite beneficiation is proved that it can improve the grade of bauxite and simplify alumina production process.This is a new way to rationally utilize the bauxite resource and develop the aluminum industry of China.
