白钨精矿含磷超过国家标准,是我矿长期没有解决的一个老大难问题。在矿党委和选矿车间党支部的重视和领导下,组织了三结合的试验小组,寻找解决的办法。由于我矿所产矿石伴生许多含磷矿物如磷灰石、磷钇矿、独居石等。这些共生含磷矿物的可浮性与白钨接近,所以在黑白钨分 Phthalate scheelite phosphorus than the national standard, mine has not been solved for a long time difficult problem. Under the attention and leadership of the coal party committee and party branch of the beneficiation workshop, a tripartite experimental group was organized to find a solution. Due to the ore produced by mine, there are many phosphorus-bearing minerals such as apatite, xenotime and monazite. The flotation of these symbiotic phosphorus-containing minerals is close to that of scheelite, so the fraction in black and white tungsten
