摘　　要：镓是一种性能优良的电子原材料,在银鼎铝土矿勘查中镓作为基本分析。对银鼎铝土矿中伴生镓的品位变化、地质特征、矿床特征、含矿岩系进行研究,讨论了铝土矿与镓在含矿岩系不同岩性段的分布特征,铝土矿和镓含量之间的线性关系及在其它矿区的适用性。进行对比研究,建立Al2O3含量与镓含量的线性方程式,确定本矿区内的镓资源储量分布规律。实践证明,通过镓的分布规律验证了基底岩石中镓含量的高低,决定了含矿岩系中铝土矿及相关岩石镓含量的高低。Gallium is an excellent electronic raw material, which was taken as a basic analysis in the exploration ofYinding Bauxite. Based on the comparative study of gallium in Yinding bauxite, the linear equation of AI203 content and gallium content was established to determine the distribution rule of gallium resources in the mine. Practice proves that, through the establishment of linear regression equation in distribution rule of gallium, the method is feasible. The distribution rule of gallium will determine the gallium content in the basement rocks, including the gallium content in the bauxite of ore rocks and the related rock.
