一前言八茎选矿厂,对铜铁矿石和钨矿石分别由单独系统处理。铜铁原矿中含0.03％WO_3的白钨矿石,一直没有有效的选矿手段,仅限于对块矿在暗室中用紫外线照射来手选白钨矿。然而,回收率仅2～3％,大部份白钨矿损失于尾矿之中。各系统的尾矿量及其WO_3含量列于表1。铜铁尾矿中的WO_3总量为160吨/年,与八茎1号钨精矿中WO_3总量166吨/年不相上下。因此,尾矿中白钨矿的回收
A foreword Bengang concentrator, the copper and iron ore and tungsten ore by a separate system. The scheelite ore containing 0.03% WO_3 in the copper and iron ore has not been effectively beneficiated and is limited to hand scheelite scheelite irradiated with ultraviolet light in a darkroom. However, the recovery rate is only 2 to 3%, most of the scheelite lost in the tailings. The tailings and WO_3 content of each system are listed in Table 1. The total amount of WO_3 in the copper-iron tailings is 160 tons / year, which is comparable with 166 tons / year of WO_3 in the tungsten concentrate of Ba-Seng-1. Therefore, the tailings scheelite recovery
