热液金矿床的矿石特点是具有固定的矿物共生组合.查明造矿矿物组合的含矿率及其中金的分配特性,具有重要的实用意义.下面对苏联某矿区金—石英—硫化物建造矿床的矿物组合和产状的研究结果作一些分析.根据专门挑选的重1—2公斤的矿样试金分析资料,来评价造矿矿物组合的含金率.为了说明各个组合的特征,沿矿体走向和倾向在各个区段采集有代表性的样品.造矿矿物之间有用组份的分布是根据单矿物研究查明的.先对样品光片用显微镜进行观察,然后把单矿物分离出来.单矿物中金和
The ore of hydrothermal gold deposit is characterized by a fixed assemblage of minerals, and it is of important practical significance to find out the ore-bearing rate and the gold distribution characteristics of the ore-bearing mineral assemblages.After the gold-quartz-sulfide The results of mineral assemblages and formations in ore deposits are analyzed and the gold content of the ore-forming mineral assemblages is evaluated on the basis of specially selected assay samples of gold samples weighing 1-2 kilograms. To illustrate the characteristics of the various combinations, A representative sample was collected in each section along the direction and tendency of the ore body.The distribution of the useful components between the ore-forming minerals was ascertained on the basis of a single mineral study.The sample light sheet was first observed under a microscope and then the single mineral Isolated. Single mineral gold and
