广西大明山钨矿为似层状砂岩型网脉状矿床。矿石属低品位细粒浸染状难选矿石。矿石含WO_3平均为0.20—0.25％。曾用单一重选流程对含WO_30.40％(其中黑钨矿占90％)。的富矿样作过试验,获得含WO_361.0％,回收率36.0％的黑钨精矿。最近,我们对原矿含WO_30.22％(其中黑钨矿占72％)的贫样进行试验。采用湿式强磁选一重选流程,获得含WO_365.89％,回收率60.08％(对黑钨矿而言)的最终钨精矿,取 Damingshan Tungsten Mine in Guangxi is a bedded sandstone network vein-like deposit. Ore is a low grade fine disseminated refractory ore. Ore containing WO_3 average 0.20-0.25%. Had a single re-election process containing WO_30.40% (including wolframite accounted for 90%). Of the ore-rich samples were tested to obtain a wolframite concentrate containing WO_ 361.0% and a recovery rate of 36.0%. Recently, we tested the crude samples containing WO_30.22% (including wolframite accounting for 72%). Using a wet magnetic screening process, a tungsten concentrate containing WO_365.89% and a recovery rate of 60.08% (for wolframite) is obtained, taking
