摘　　要：简述了桂西堆积型硬水铝石三水铝石铝土矿矿床地质特征及三水铝石赋存状态,对堆积型铝土矿基质中的三水铝石进行了定量分析和溶出试验,结果表明:32.9%的样品达到边界品位;其最低溶出率达到95.5%。该三水铝石矿具有溶出性能好、冶炼成本低,经济价值高等优点。桂西是我国最重要的三水铝石资源产地,具有良好的综合利用前景。This paper briefly described the geological features of accumulated bauxite composed of diaspore and gibbsite,and the occurrence state of gibbsite. Quantitative analysis and digesting test for gibbsite in matrix from accumulated bauxite have been carried out. The analytical results showed that 32.9 percent of the analyzed samples reaches the cut-off grade. Digesting test results of gibbsite proved that its lowest digesting rate reaches 95.5 percent. The gibbsite is characterized with high digesting rate and low smelting cost and high economic value. Western Guangxi province is one of the most important mining areas of gibbsite deposite and has wide prospects for comprehensive utilization.
