古云锡矿是1981年冬引进外资补偿贸易兴建的小型锡矿山。矿山建设采选规模为50吨/日,选矿厂主要生产工艺流程为重选。1.原矿性质。古云锡矿矿床属云英岩型锡矿床。矿体呈囊状产出;其产状与形状较为简单。矿体长约90米,中部厚度约30米,延深70—83米,向深延伸约40米,具有工业开采价值,往下趋于尖灭。矿石含锡由上部0.37%降至下部0.19%,平均锡品位0.33%。矿化深度不大。矿石有致密块状及浸染状构造,为浸染状锡矿
Guyun Tin Mine is the introduction of foreign investment in winter 1981 to compensate for the construction of small tin mines. Mining construction and mining scale of 50 tons / day, concentrator main production process for re-election. The nature of the ore Guyun tin deposit is a dolostone type tin deposit. The ore body is cystic output; its production and shape is relatively simple. The ore body is about 90 meters in length with a thickness of about 30 meters in the middle, a depth of 70-83 meters and an extension of about 40 meters in depth. It has the value of industrial exploitation and tends to get out of control. Tin ore from the top 0.37% down to the bottom of 0.19%, the average grade of 0.33% tin. Mineralization is not deep. Ore has a dense block and disseminated structure for the disseminated tin
