篦子沟铜矿属细脉浸染型似层状矿床,主要金属矿物为黄铜矿,其次为斑铜矿、辉铜矿、黄铁矿、磁黄铁矿、闪锌矿等。非金属矿物主要有方解石、石英、黑云母,其次为绢云母、白云母等。选矿厂采用优先选铜再选钴的流程。过去现场对木质素的添加方法不当,在时间和添加量上都没有严格控制,基本上只起到调节泡沫层厚度的作用,使铜精矿品位一直很低。为此,选矿厂通过小型试验和 Gouzigou copper deposit is veinlet disseminated layered deposit, the main metal minerals are chalcopyrite, followed by beetle, chalcopyrite, pyrrhotite, sphalerite and so on. Non-metallic minerals are mainly calcite, quartz, biotite, followed by sericite, muscovite and so on. The beneficiation plant chooses the process of preferential copper re-selection of cobalt. In the past on the site of improper addition of lignin in the time and dosage are not strictly controlled, basically only play a role in regulating the thickness of the foam layer, so that the grade of copper concentrate has been very low. To this end, concentrator through small trials and
