俄罗斯某钨矿含WO30．36％，S 2．37％。矿石中钨矿物主要为黑钨矿，黑钨矿中的WO3占91．89％，白钨矿中的WO3仅占8．11％；硫矿物为黄铁矿、磁黄铁矿；脉石矿物主要为石英、云母，其次为长石，另外有少量的绿泥石、萤石，微量的方解石、磷灰石、金红石，菱锰矿、绿帘石、榍石等。针对该矿石特点，采用“螺旋溜槽＋悬振锥面选矿机粗选—粗精矿摇床精选—重选粗精矿浮选脱硫—摇床精选”工艺流程，实验室可获得含WO365．07％，回收率78．15％的钨精矿。

Acertaintungsten ore(containing WO3 0 .36% ,S 2 .37% )is from Russia .The main tungsten mineral is wolframite ,of which WO3 accounts for 91 .89% of the total WO3 ,and the rest of WO3consists in scheelite ,which makes up 8 .11% of the total WO3 .Except forwolframite and scheelite ,this tungsten ore also contains pyrite ,pyrrhotite ,quartz ,mica ,feldspar ,chlorite ,calcite ,fluorite ,apatite ,JinHongshi , rhodochrosite ,epidote ,titanite ,and so on .Based on the properties of the ore ,a beneficiation flowsheet of“roughing of spiral chute + hang vibrate of cone concentrator‐rough concentrate cleaning by the table concentrator‐sulfur separation of rough concentrate‐cleaner by the table concentrator” was adopted .The tungsten concentrate of 65 .07% WO3 with recovery 78 .15% was obtained .
