Quartz vein containing gold ore material composition is relatively simple, mainly composed of quartz, its content is 50% ~ 95%, metal mineral content is less than 15%. Pyrite is the main sulfide minerals, followed by pyrrhotite and minor galena, chalcopyrite etc.. The gold deposits are mainly free of natural gold, and the occurrence of the state is simple, and most of them are symbiotic with quartz and pyrite. Alternative classification of quartz vein gold bearing ores       矿石类型    Ore type       特征    Features       可选性及选矿方法    Alternative and mineral processing methods       I    I       石英质含金矿石    Quartz gold bearing ore       矿石中基本成分是石英（含量90%以上），金属矿物为自然金，几乎没有重金属、硫化物、金粒以为粒居多。    The basic composition of the ore is quartz (content of more than 90%), metal minerals as natural gold, almost no heavy metals, sulfide, gold grains are mostly.       粗粒嵌布的矿石很容易用混汞和重选法从中回收金、细粒嵌布的矿石，用背负浮选法活氰化法处理。    Coarse grain disseminated ore is very easy for the amalgamation and gravity separation and recovery from gold, fine disseminated ore by flotation, with live cyanidation.       含少量硫化物    Containing a small amount of sulfide       石英脉含金砂石    Quartz vein gold bearing sandstone       Ⅱ    II       金与硫化物共生关系密切    Gold and sulfur are closely related to the symbiotic relationship       金属矿物以黄铁矿为主，硫化物含量1～5%，脉石矿物以石英为主，自然金60%以上和硫化物共生，金以中细粒居多。    The metal minerals are pyrite, sulfur content of 1 ~ 5%, the main gangue mineral is quartz, gold sulfide and natural symbiosis of more than 60%, with fine gold.       属易选矿石，适于用浮选法回收，浮选精矿可氰化处理。    Ore is easy to choose, suitable for recovery by flotation, flotation concentrate can be treated with cyanide.       Ⅲ    III       金与石英共生关系密切    Gold and quartz are closely related to the symbiotic relationship       金属硫化物含量较少，70%的金与石英等脉石矿物共生，粒度较细，矿石基本不含砷、锑、铜等元素。    The metal sulfide content is less, 70% of the gold and gangue minerals such as quartz, fine granularity, the basic content of arsenic and antimony ore, copper and other elements.       适于用浮选法回收浮选精矿可氰化；混汞或重选法做为辅助方法回收粗粒金。    Is suitable for cyanide by flotation recovery of flotation concentrate; amalgamation or gravity method is used as an auxiliary method for recovery of coarse gold.       Ⅳ    IV       黄铁矿含金石英脉矿石    The pyrite bearing quartz vein ore       矿物组成与矿石Ⅱ相近，主要差别在于硫化物含量高（5～15%），金75～99%。与黄铁矿密切共生。    The mineral composition is similar to that of the ore, the main difference is that the content of sulfide is high (15% ~ 5), and gold is 75 to 99%. Closely associated with pyrite.       易于浮选，指标高达95%以上，浮选精矿含硫较高，可综合利用。    Easy to flotation, index up to 95% or more, high sulfur flotation concentrate, can be integrated use.       石英脉含金    Quartz vein gold       氧化矿石    Oxidized ore       Ⅴ    V       部分氧化矿石    Partially oxidized ore       主要金属矿物为褐铁矿，亦含少量黄铁矿，脉石为石英，玉髓质石英等，金赋存于脉石矿物和金属矿物之裂隙中，含有含金的氢氧化铁是该矿石矿物组成的主要特点。    The main metal mineral is pyrite and limonite, also, gangue is quartz, chalcedony quartz, gold occurrence in the gangue minerals and metal minerals in fracture, containing ferric hydroxide is the main characteristics of the gold ore mineral composition.       以混汞（重选）加全泥氰化或加浮选法浮选为主。    The amalgamation (gravity) plus whole mud cyanidation or flotation flotation.       Ⅵ氧化矿石    VI oxidized ore       不含硫化物，金大部分赋存在主要脉石矿物以及经风化后的金属氧化物残留颗粒中，含泥质。    Nonsulfide gold, most exist the main gangue mineral and metal oxides after weathering residual particles, containing mud.       不宜采用浮选法    Flotation process should not be adopted.       粗粒金用混汞及重选法回收，然后分级，矿泥搅拌氰化，矿砂渗沪氰化。    Coarse grained gold by amalgamation and re recovery, then grading, mixing ore slime cyanidation, infiltration Shanghai cyanide.
