| 摘 要： | 水银洞超大型金矿床金赋存于沿沉积型自形半自形黄铁矿内核生长成的含砷黄铁矿环带中。近来从水银洞金矿床原生富矿石（碳酸盐岩型矿石）中一条含砷黄铁矿细脉中发现100余粒次显微-显微自然金颗粒（0.1~6μm）,通过对金的赋存状态及预氧化提金后尾渣的研究,认为矿石破磨至325目有可能损失部分金和系统中黄铁矿出现过氧化现象,从而... |

| Abstract: | The Shuiyindong super-large gold deposit occurred in the arsenian pyrite zone which grown around the euhedral and semi-euhedral sedimentary pyrite core.Recently,over 100 micron-submicron sized gold particles（0.1～6μm） have been observed in arsenic-bearing pyrite veinlets in the primary ore carbonate type ore） in the Shuiyindong deposit.On the basis of the studies on the gold occurrence state of the primary ore and the tailing,it is suspected that a small part of gold could be lost in the grinding process and the cost of oxidizing gold-bearing arsenian pyrite by NaOH could be much higher than it should be due to the over oxidation of pyrite because the ordinary ore was grinded to less than 325 mesh in size. |
