贵州铝土矿伴生镓的分布特征及综合利用前景——九论贵州之铝土矿

Characteristics of Associate Gallium Distributed in the Bauxite in Guizhou and Its Prospects for Comprehensive Utilization: Nine Treatments of Bauxite Ores

镓是甚为分散的元素，由于镓和铝的性质相近，大量镓伴生于铝土矿中。在黔中-渝南成矿带内，除修文矿带铝土矿镓平均含量为63×10^-6外，息烽、遵义、正安、道真矿带铝土矿中镓平均含量为114×10^-6～129×10^-6。铝土矿中镓含量高低，可能与其基底地层岩石中镓含量的高低关系密切。贵州铝土矿中镓的平均含量皆大大超过铝土矿中镓的综合利用指标，有着广泛的开发利用前景。

Gallium is a mostly disperse element that associates abundantly in the bauxite since its property similar to aluminum. Gallium contents in the bauxite average 114 × 10^-6 ～ 129 × 10^-6 in Xifeng, Zunyi, Zheng＇an and Daozhen ore belts in the metallogenic areas of Central Guizhou and South Chongqing, except for 63 × 10^-6 in Xiuwen ore belt. Gallium contents in the bauxite are closely associated to that within the rocks of the basement beds. Average gallium content significantly exceed the index of gallium integrated utilization in the bauxite in Guizhou. there occur widespread prospects for development and exploitation.
