湘东钨矿是个多金属矿山,由于矿石性质复杂,矿物共生密切,建矿以来,钨精矿质量一直较低,钨一级品率只有10～40％。近来,该矿改进精选工艺,加强管理,去年8月份以来,钨一级品率已达到100％,钨、铜回收率也有一定程度的提高。全年净收入增加13万元。现把情况分述如下。 (一)矿石性质湘东钨矿属高、中温热液裂隙充填,多次成矿的含钨石英脉矿床。主要矿物有黑钨矿、白钨矿、黄铜矿、锡石、毒砂、闪锌矿等,主要脉石矿物为石英、方解石、白云母、萤石
The Xiangdong tungsten deposit is a polymetallic mine. Due to its complicated nature and close association of minerals, the quality of the tungsten concentrate has been relatively low since the founding of the mine. The first-class tungsten product rate is only 10-40%. Recently, the mine has improved the selection process and strengthened its management. Since August last year, the tungsten-grade product rate has reached 100%, and the recovery rates of tungsten and copper have also been raised to some extent. Annual net income increased 130,000 yuan. The situation is divided as follows. (A) ore properties Xiangdong tungsten ore is a high, medium temperature hydrothermal fissure filling, multiple tungsten-bearing quartz vein deposits. The main minerals are wolframite, scheelite, chalcopyrite, cassiterite, arsenopyrite, sphalerite, etc., the main gangue minerals quartz, calcite, muscovite, fluorite
