摘要
在分析我国铝土矿矿石特点和总结以往铝土矿选矿试验及 1999年工业试验成果的基础上 ,通过对选矿拜耳法与原矿混联法的技术经济比较 ,论证了铝土矿选矿工艺 ,可提高矿石品位 ,简化氧化铝生产流程 。
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.
