新疆某低品位钼矿石钼品位仅0．076%。矿石中除钼外,还伴生含量为0．033%的铜和含量为1．232%的硫。虽然钼、铜、硫主要以辉铜矿、黄铜矿、黄铁矿形式存在,但它们共生关系密切,分离困难。根据矿石性质开展综合回收钼、铜、硫的选矿试验,首先将原矿粗磨至-0．074 mm占85%后进行钼铜硫的混合浮选,然后将钼铜硫混合精矿细磨至-0．043 mm占95%后进行钼铜与硫的分离浮选,最后对钼铜混合精矿进行钼与铜的分离浮选,并在钼铜硫混合浮选过程中使用新型捕收剂GZW101和新型抑制剂GTS、在钼铜分离浮选过程中使用新型抑制剂GLN,最终获得了钼品位为47．03%、钼回收率为73．20%的钼精矿以及铜品位为14．89%、铜回收率为77．26%的铜精矿和硫品位为54．26%、硫回收率为88．94%的硫精矿,从而为该矿石的高效利用提供了依据。
新疆某低品位鉬礦石鉬品位僅0．076%。礦石中除鉬外,還伴生含量為0．033%的銅和含量為1．232%的硫。雖然鉬、銅、硫主要以輝銅礦、黃銅礦、黃鐵礦形式存在,但它們共生關繫密切,分離睏難。根據礦石性質開展綜閤迴收鉬、銅、硫的選礦試驗,首先將原礦粗磨至-0．074 mm佔85%後進行鉬銅硫的混閤浮選,然後將鉬銅硫混閤精礦細磨至-0．043 mm佔95%後進行鉬銅與硫的分離浮選,最後對鉬銅混閤精礦進行鉬與銅的分離浮選,併在鉬銅硫混閤浮選過程中使用新型捕收劑GZW101和新型抑製劑GTS、在鉬銅分離浮選過程中使用新型抑製劑GLN,最終穫得瞭鉬品位為47．03%、鉬迴收率為73．20%的鉬精礦以及銅品位為14．89%、銅迴收率為77．26%的銅精礦和硫品位為54．26%、硫迴收率為88．94%的硫精礦,從而為該礦石的高效利用提供瞭依據。

There is 0. 076% Mo in a low grade molybdenum ore from Xinjiang,and also 0. 033% Cu and 1. 232% S as-sociated with molybdenum. Molybdenum,copper and sulfur mainly exist in forms of molybdenite,chalcopyrite,and pyrite,but it is difficult to be separated from each other for their close intergrowth. Beneficiation experiment on comprehensive recovery of molybdenum,copper,and sulphur was conducted based on the ores properties. Firstly,Mo-Cu-S bulk flotation tests were con-ducted after grinding the raw ore at 85% -0. 074 mm. Secondly,separation flotation of molybdenum-copper from sulfur were carried out after grinding the rough Mo-Co-S concentrate. Then,molybdenum-copper bulk concentrates were put into the separa-tion flotation of molybdenum from copper. Novel collector GZW101 and depressor GTS were used in Mo-Cu-S bulk flotation,al-so new depressor GLN was brought in separation flotation of molybdenum and copper. Molybdenum concentrate with 47. 03%Mo and recovery of 73. 20%,copper concentrate with 14. 89% Cu and recovery of 77. 26%,and sulfur concentrate with 54. 26% S and recovery of 88. 94% was obtained. The flotation results provide basis for high efficient utilization of the ore.
