On the process mineralogy of lead-zinc oxides ore in Shanxi’s Nanmushu

The resources of a lead-zinc oxide ore in Shaanxi’s Nanmushu area is very rich. Make good use of it has a great realistic significance for Shaanxi’s lead-zinc industry. The lead-zinc oxide ore in Shaanxi’s Nanmushu area is studied from the perspective of technological mineralogy. The features of process mineralogy of lead-zinc oxides ore, including the chemical composition, mineral composition, the granularity of smithsonite and the structure of ore is studied in detail by various means in the paper. The main metal minerals include Pyrite, sphalerite and a little of Willemite and pyrite, and so on. Gangue minerals include Dolomite and quartz.The ore structure is complex. It provides the theoretic basis for the choice of mineral processing technique and exploitation of lead-zinc oxides ore in Shanxi’s Nanmushu.
