我国铝土矿资源及其选矿技术进展

阐述了我国铝土矿的资源储量与进口情况，介绍了我国铝土矿资源类型与特点，并分析了铝土矿资源开发存在的问题。针对我国铝土矿资源较为丰富但质量差的特点，总结了所采用的铝土矿选矿方法。并从铝土矿选矿脱硅、高铁铝土矿铝铁分离与高硫铝土矿脱硫、铝土矿选矿尾矿和废水处理三个方面分析了目前铝土矿选矿存在的工艺技术问题。建议立足国内资源，淘汰落后产能，推进铝土矿选矿与尾矿和赤泥的资源化利用研究，并加大利用国外铝土矿资源力度以及开发利用其他铝资源。 

Current Situation of Bauxite Resource and Its Beneficiation Technology in China

This paper expounded the resource reserves and the import situation of bauxite in China. The resource types and characteristics of bauxite resources in China were introduced. Meanwhile, the problems existing in the development and utilization of bauxite resources were analyzed. Based on the characteristics of abundant resources but poor quality of bauxite resources in China, the mineral processing methods of bauxite were discussed. The technical issues of bauxite mineral processing from three aspects were analyzed. The existing technical problems of bauxite beneficiation were analyzed from three aspects:desilication by bauxite beneficiation, separation of bauxite and iron from high-iron bauxite and desulfurization by high-sulfur bauxite, tailings from bauxite beneficiation and wastewater treatment. Some suggestions have been put forward, such as eliminating backward productivity based on domestic resources, promoting research on bauxite beneficiation and utilization of tailings and red mud, and increasing the utilization of foreign bauxite resources and developing and utilizing other bauxite resources.
