云台山硫铁矿位于南京市南郊,目前实际生产能力为30万吨/年。矿体为中温热液充填交代矿床,走向长750米,延深约200米,倾角30～50°。硫铁矿体多呈不规则透镜状产出,共80余条,但在矿区北端较连续和集中,少夹层,形成走向长近200米、水平厚度达150米的膨大厚矿体,是近期应用无底矿分段崩落法开采的主要矿段;矿区南端的矿体较断续零散,变化很大,水平厚度2～30米。 黄铁矿石呈浸染、致密状,f=9～15。平均含硫33.67％的Ⅰ级品富矿质地较软,
Located in the southern suburbs of Nanjing, Yuntaishan Pyrite Mine currently has an actual production capacity of 300,000 tons / year. The ore body is mesothermal hydrothermal filling metasomatic deposit, to 750 meters long, about 200 meters deep, inclination 30 ~ 50 °. Most of the pyritiferous ore bodies are irregularly lenticular in shape with a total of more than 80 pieces. However, the northern end of the ore district is more continuous and concentrated with less interlayer formation and the formation of swelled thick ore bodies with a length of nearly 200 meters and a horizontal thickness of 150 meters is the recent The main ore section exploited by subsea caving and subsided caving method is applied. The ore body at the southern end of the mining area is quite fragmented and varies greatly, with a horizontal thickness of 2 to 30 meters. Pyrite was disseminated, dense, f = 9 ~ 15. The average sulfur content of 33.67% Ⅰ grade rich mineral soft,
