在五龙金矿四道沟分矿党组织领导下,选矿厂近年来曾多次用咪唑代替黄药作捕收剂进行了试验考察,初步得出了结论。 四道沟分矿的矿石产于断裂带中裂隙充填型含金石英脉型矿床。矿石含金4～7(克/吨)。金属矿物种类少,组成比较简单。主要金属矿物有黄铁矿、黄铜矿,自然金等。自然金主要赋存在黄铁矿中,其含量约占自 Under the leadership of the Sidao ditch mining party organization of Wulong gold mine, in recent years, the concentrator has conducted experiments and tests with imidazole instead of xanthate as collector for many times, and has initially come to the conclusion. The ore of the Sidaogou sub-ore is produced in fractured-filled gold-bearing quartz vein type deposits in the fault zone. Ore gold 4 ~ 7 (g / ton). Metal minerals less, the composition is relatively simple. The main metal minerals are pyrite, chalcopyrite, natural gold and so on. Natural gold is mainly found in pyrite, its content accounts for about
