桂西堆积型铝土矿伴生钛资源潜力及综合回收利用
Potential and comprehensive recovery and utilization of associated titanium resources in accumulation-type bauxite of western Guangxi
摘要
Abstract
Bauxite is often associated with various critical metal elements such as gallium(Ga)and titanium(Ti).Studying the potential and comprehensive recovery and utilization of associated titanium resources in the accumula-tion-type bauxite in western Guangxi is conducive to the efficient utilization of mineral resources.This paper sys-tematically collected the resource reserve data and ore quality characteristics of major accumulation-type bauxite deposits in western Guangxi,conducted a detailed survey on the current status of associated titanium resource utili-zation by major aluminum enterprises in the region,and focused on carrying out process mineralogy and ore benefi-ciation & metallurgical performance tests in the bauxite mining area on the periphery of Taiping,Pingguo City,Guangxi.On this basis,a comprehensive recovery and utilization process was proposed.The research shows that the associated titanium resources in the accumulation-type bauxite in western Guangxi are abundant,with the average content of titanium dioxide(TiO2)ranging from 3％to 4％.The TiO2 in the ore mainly exists in the form of ana-tase,which is difficult to be comprehensively recovered and utilized during the alumina production process.As a result,TiO2 is further enriched in red mud,with its average content reaching approximately 6％.The comprehen-sive recovery and utilization of critical metal resources such as TiO2 can be achieved through a process that first re-moves calcium and extracts iron from red mud,followed by extracting elements including titanium,scandium(Sc),and rare earths.关键词
