Study on Process Mineralogy of Laodong Zhai Lead-Zinc Deposit, Danzhai County, Guizhou Province
-
Abstract
Laodong Zhai Lead-zinc deposit is located in Danzhai County, Guizhou Province. Lead-zinc ore bodies mainly occur in the Sinian Doushantuo Formation (Pt3d). 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.
