摘　　要：黄金(Au)因其稀有及稳定的化学性质,已成为重要的战略金属和贵金属,在许多方面和领域得到了广泛的应用。金矿床常伴生一些贱金属,如铅、锌、银、铜等,对它们综合利用可获得较高经济价值。本文讨论了热液矿床中金、铅、锌、银、铜的迁移及沉淀机制,借此为各个金矿床进一步工作提供参考。笔者还介绍了判别金矿成矿流体地球化学过程的部分特征,将有利于判断流体中发生的地球化学变化,进而了解成矿过程及矿化有利部位,为进一步找矿提供依据。Gold(Au)has been an important strategic metal and precious metal because of its rare and stable chemical properties,and has been widely used in many aspects and domains.Gold deposits may often associated with some kinds of base metal like lead,zinc,silver,copper,etc.,we can gain higher economic value through the comprehensive utilization of these metals.In this paper,we will discuss the migration and precipitation mechanism of gold,lead,zinc,silver and copper,so as to provide reference for the further work of each gold deposit.On the other hand,the author introduces some characteristics to distinguish the geochemical process of gold ore-forming fluid,which will be helpful to judge the geochemical changes in the fluid,and then knows about the ore-forming process and the favorable position of mineralization,and provide the basis for further prospecting.
