摘要
老冬寨铅锌矿位于贵州省丹寨县,铅锌矿体主要赋存于震旦系陡山沱组(Pt_(3)d)容矿地层中。本文采用化学分析、显微镜分析、X射线衍射以及电子探针分析分析测试手段,对老冬寨铅锌矿进行了工艺矿物学研究。研究结果表明,原矿综合样中闪锌矿含量为15.02%,方铅矿含量为0.81%,另见少量黄铁矿、黄铜矿;脉石矿物主要为石英(56.21%),其次为白云母(15.2%)和高岭石(6.55%),以及少量白云石、方解石等。Pb和Zn的主要载体矿物分别为方铅矿和闪锌矿,理论回收率分别为98.60%和87.90%.
Laodong Zhai Lead-zinc deposit is located in Danzhai County,Guizhou Province.Lead-zinc ore bodies mainly occur in the Sinian Doushantuo Formation(Pt_(3)d).In this paper,the process mineralogy of Laodong Zhai Lead-zinc deposit was studied by means of chemical analysis,microscope analysis,X-ray diffraction and electron probe analysis.The results show that the content of sphalerite and galena is 15.02%and 0.81%respectively,in raw ore comprehensive sample.Gangue minerals are mainly quartz(56.21%),followed by Muscovite(15.2%),kaolinite(6.55%),and a small amount of dolomite,calcite and so on.The main carrier minerals of Pb and Zn are galena and sphalerite,with theoretical recovery rates is 98.60%and 87.90%,respectively.
