摘　　要：这是一篇工艺矿物学领域的论文。采用化学分析、显微镜分析和MLA矿物自动定量检测技术,对国内某锌矿石中锌及伴生稀散元素镓、锗的赋存状态和主要载体矿物的嵌布特征进行详细研究。结果表明,该锌矿石中含Zn 4.87%、Ga 4.10 g/t、Ge 59.00 g/t,未发现稀散元素镓、锗的独立矿物,镓、锗主要赋存在闪锌矿中。从该矿石中分选闪锌矿(包含异极矿),锌、镓、锗的理论回收率分别为95%、56%、93%左右。少部分微细粒状胶态闪锌矿不易获得解离,易损失于尾矿中,对锌的回收率有一定影响。This is an article in the field of process mineralogy.The occurrence of zinc,associated dispersed elements Ga and Ge and the distribution characteristics of the main carrier minerals of a zinc ore in China are studied in detail by means of chemical analysis,microscope analysis and MLA mineral automatic quantitative technology.The results indicate that the zinc ore contains Zn 4.87%,Ga 4.10 g/t and Ge 59.00 g/t,no independent minerals of dispersed elements Ga and Geare found,Ga and Ge mainly occur in sphalerite.The theoretical recovery of Zn,Ga and Ge from sphalerite(including hemimorphite)are about 95%,56%and 93%respectively.A small part of colloidal and fine grained sphalerite is difficult to obtain dissociation and easy to be lost in tailings,which has a certain effect on the recovery of zinc.
