湘西金矿沃溪矿区矿床为金、锑、钨石英脉大型矿床。主要金属矿物为自然金、辉锑矿、黄铁矿、毒砂、白钨矿、钨铁矿。主要脉石矿物为石英、方解石、绢云母等。原矿含Au、sb、WO_3分别为4(克/吨)、1.5%、0.2%。金的嵌布粒度细,大于0.2毫米的可见金极少,约70%为显微金,15%为次显微金(-0.5微米)。充填于石英、白钨矿间隙的金颗粒稍大;黄铁矿、辉锑矿、毒砂中的金颗粒较细,但在浮选硫化矿物时较易回收;伊利石、石英中的次显微金系难选矿物。生产中采用重浮联合流程回收金、锑、钨三种
The deposit of Woxi Mining Area in Western Hunan Gold Deposit is a large-scale deposit of gold, antimony and tungsten quartz veins. The main metal minerals are natural gold, stibnite, pyrite, arsenopyrite, scheelite, and ferratite. The main gangue minerals are quartz, calcite, sericite and so on. Raw ore containing Au, sb, WO_3 were 4 (g / t), 1.5%, 0.2%. The fineness of the gold inlay is fine, with less than 0.2 mm of visible gold, about 70% of which is micro-gold and 15% of sub-micro-gold (-0.5 microns). Fill the quartz, scheelite gap gold particles slightly larger; pyrite, stibnite, arsenopyrite gold particles smaller, but more easily recovered in the flotation of sulfide minerals; illite, quartz secondary significant Micro-gold refractory minerals. Recycling production processes used in the recovery of gold, antimony, tungsten three
