摘　　要：广西作为我国铝资源大区,已探明铝土矿储量约8亿t,远景储量超10亿t,占全国铝土矿资源总量的24%以上。本文采用XRD、ICP-AES及XRF等对广西百色铝土矿的成分分析。另外,在铝土矿粉末中添加一定量的黄铁矿在900℃下焙烧,焙烧时间为20,40和60 min,结果显示,其氧化锌的含量随焙烧时间增加而减少。Guangxi,as China’s aluminum resources region,has proved bauxite reserves of about 800 million tons,prospective reserves of more than 1 billion tons,accounting for more than 24%of the country’s total bauxite resources.In this paper,XRD,ICP-AES and XRF are used to analyze the composition of Baise bauxite in Guangxi.In addition,certain amount of pyrite was add to bauxite powder to be calcinations at 900℃,and the time was controlled at 20,40,60 min.The results showed that the content of Zinc oxide decreased with the increase of calcination time.
