Immoderate discharge of mine water not only wastes a great deal of precious water resources, but also increases the cost of per ton coal and causes some environmental problems such as ground collapsing, ground water resource loss, water quality deterioration and so on. Therefore, rational utilization of mine water as resource is the best choice of solving the water source problem of mine site and pithead power plant and the environmental problem of mine water pollution.

本文在分析彬长矿区地质及水文地质条件的基础上，分别用"大井法"和水文地质比拟法计算了亭南井田、大佛寺井田、胡家河井田和小庄井田四矿的矿井涌水量，分析四矿矿井向大唐彬长坑口电站的供水能力，并对矿井水的水质进行了评价，研究了矿井水作为电站供水水源的可行性。

According to logging results of 167 boreholes and chemical analyses of 24 369 samples as well as characteristics of element distribution at 4 000 m, 3 950 m and 3 900 m levels, the deposit is characterized by alteration, mineralization and element geochemistry of the porphyry. Alteration and mineralization are spatially and temporally related to the augen quartz phenocryst_bearing hornblendequartz diorite porphyrite (J3δομ).

根据167个勘探钻孔编录和化学分析（24369件化学分析样品）资料，以及对海拔4000 m、3950 m、3900 m水平面的Cu、Au、Ag、Mo、Mn、P b、Zn、W、K、Na、Ca、Rb元素分布规律的分析，显示矿体具有斑岩型矿床的蚀变、矿化以及元素地球化学特征，主要矿化和围岩蚀变在时间上和空间上均与含眼球状石英斑晶的角闪石英闪长玢岩（J3δομ）有关。

北京矿冶研究总院和凡口铅锌矿共同研发的新四产品工艺流程，其原则流程为快速浮选得高铅精矿和高锌精矿、铅锌中矿合并细磨混合浮选得铅锌混合精矿。

The effects, such as the acidity of leaching system, the temperature and the concentration of the sodium chloride, on oxidation and leaching of copper-bearing gold ores were analyzed. The results show that the sequence of sulfide ores oxidized and dissolved are pyrrhotite firstly, sulphide secondly, then chalcopyrite, pyrite lastly.

结果表明：硫化矿的氧化溶解首先是磁黄铁矿，其次是铜的次生硫化矿，再次是黄铜矿，最后是黄铁矿；载金黄铜矿的氧化首先是铁从黄铜矿的晶格中氧化溶解出来，生成中间产物CuS2和CuS；较高的酸度和氯化钠浓度有利于单质硫的生成、三价铁的水解和铜的浸出，进而有利于金浸出率的提高。
