The ore to be discussed here is a primary copper-gold ore containing a large amount of pyrite occurred in the quartz Lode. The gold in the ore is on intimate terms with sulphur and copper because it exsits mainlyin ferric sulphide and copper sulphide. Golds distribute in the ore unevenly and most of them are within or/and between the grains of Pyrite,Based on the facts metioned above, it is necessary to separate a pyrite concentrate, besides a copper-gold concentrate, from the Au-Cu-FeS2 ore in mineral processing,...

Golds distribute in the ore unevenly and most of them are within or/and between the grains of Pyrite,Based on the facts metioned above, it is necessary to separate a pyrite concentrate, besides a copper-gold concentrate, from the Au-Cu-FeS2 ore in mineral processing, find how to reduce the gold content in pyrite concentrate becomes a main problem.In this paper, some treatment options such as one-stage grinding and concentration,cyanidation,amalgamation-flotation, and flotation in stages, etc were studied, a reasonable treatment option selected and good results obtained.

高硫原生含铜金矿石,是一种含硫化铁较高的铜金石英脉矿石。由于金主要赋存在硫化铁和硫化铜中,金与硫、铜的关系密切。金在矿石中呈不均匀嵌布,包裹金与粒间金占优势。鉴于上述情况,在选矿工艺中除产出一个含铜金精矿外,还需从Au—Cu—FeS_2混合金矿中分离出一个硫精矿。如何降低硫精矿中金含量就成为一个突出的问题。本文通过对一段磨选、氰化浸出、混汞浮选、阶段浮选等处理方案进行的探讨、寻求了合理的选别方案,取得了较好的指标。

it is now found out that more and more gold deposits occurring in Archean massifs are almost syn-tectonic shear zone-type deposits. Their ore-hosted faults were formed by hydraulic fracturing during the driving of tectonic stress, that is, ore-bearing fluid promoted cracks to generate and propagate, and then form fractures. Once fractures were formed,ore-bearing fluid was quickly pumped into and precipitated in them, and then fractures were sealed. Unceasing supply and precipitation of the fluid produced cyclic...

it is now found out that more and more gold deposits occurring in Archean massifs are almost syn-tectonic shear zone-type deposits. Their ore-hosted faults were formed by hydraulic fracturing during the driving of tectonic stress, that is, ore-bearing fluid promoted cracks to generate and propagate, and then form fractures. Once fractures were formed,ore-bearing fluid was quickly pumped into and precipitated in them, and then fractures were sealed. Unceasing supply and precipitation of the fluid produced cyclic fluctuations in fluid pressure, and they were shown to control the repeated "crack-sealing" of fracture-vein systems, and multiperiodic gold-bearing quartz veins were formed.

现在发现越来越多的产在太古代地块中的金矿床大多都是同构造剪切带型矿床,其容矿断裂是在区域构造应力作用下由液压致裂作用所形成,即含矿流体驱动裂纹的产生和扩展,并形成裂隙。而矿体中最重要的矿石类型──含金石英脉为同构造脉,即含矿流体紧随裂隙的张开而快速沉淀其中,形成含金脉体,并使裂隙愈合。含矿流体的不断补给和沉淀,使流体的压力发生周期性的波动,而这种波动的流体压力使"裂隙-脉体"系统发生周期性的裂开-愈合作用,由此形成了富金的多期多阶段的复式石英脉体。

The Jinshan shear zone-hosted gold deposit mainly consists of two types of ores, the auriferous siliceous mylonite type and the auriferous quartz vein type.They were formed in the first and the second stages of mineralization, respectively.The auriferous siliceous mylonite is similar in geochemical characteristics of REE and trace elements to the country rock, which may have provided ore-forming matrials for the first stage of mineralization. The chemical and isotopic characteristics of the fluid inclusions...

The Jinshan shear zone-hosted gold deposit mainly consists of two types of ores, the auriferous siliceous mylonite type and the auriferous quartz vein type.They were formed in the first and the second stages of mineralization, respectively.The auriferous siliceous mylonite is similar in geochemical characteristics of REE and trace elements to the country rock, which may have provided ore-forming matrials for the first stage of mineralization. The chemical and isotopic characteristics of the fluid inclusions from the auriferous quartz veins indicate that the oreforming fluid responsible for the second stage of mineralization came from meteoric water, and the main factor to cause gold precipitation is the phase separation of fluid.

金山剪切带型金矿床主要发育含金硅质糜棱岩和合金石英脉两类矿石,它们分别在矿化第一和第二阶段形成。含金硅质糜棱岩与围岩一双桥山群上亚群具有一致的稀土和微量元素分布特征及相近的元素比值,后者为矿床第一阶段矿化的形成提供了物质来源。含金石英脉中流体包裹体的化学和同位素组成特征表明,矿化第二阶段的成矿流体为源于大气降水的地下热水,引起自然金沉淀的因素主要是流体的相分离。
