| 摘 要： | 镓是一种价格昂贵的稀贵金属，它的回收利用问题逐渐引起人们的重视。在对杜家沟铝土矿床矿石中镓的分布特征做了多方面对比研究的基础上，归纳出镓的分布规律：空间上、镓在不同层位的矿石中平均含量变化显著，镓含量随着矿层平均厚度的增大而增大。遭受强烈的表生富集作用，铝土矿中镓的平均品位较高。从矿石结构类型来看，蜂窝状矿石中的镓品位明显高于豆、鲕状和致密状矿石。另外，另外，矿石中镓的含量总与富矿体关系密切。

| Abstract: | Gallium is one kind of rare and precious metal, and the prospect of its application is very bright. The development and exploitation prospects of Gallium resource in Henan bauxite gradually have become a hot issue in the field of comprehensive utilization of nature resources. Based on multilaterally comparative study, the distribution laws of gallium in Du Jiagou bauxite ore in the western areas of Henan Province are induced as follows. (1) Space Distribution. The average content of Gallium in different bauxite ore beds has large change. And the content becomes high with the increase of ore beds; (2) Texture Type of Ore. Because of intensive epegenetic enrichment, the average content of Gallium in honeycomb structure is higher than that in pisolitic, oolitic structure and massive structure. Besides, the content of Gallium in ore always has great relationship with ore shoots. |
