Abstract: The mineralogy of the greisen in Shirenzhang in Guangdong was studied in this article, on the basis of the study, the metallic minerals of copper, molybdenum, bismuth, wolfram and stannum and the nonmetallic mineral of quartz were the high value products.On the basis of the ore nature, flotation can be used to select to copper, molybdenum, bismuth and white mica, then the wolfram and stannum minerals can be selected. There are a wide variety of complex minerals in the ore, and has high value for comprehensive utilization and recycling economy.
