摘要
普朗斑岩型铜矿具典型的斑岩铜矿蚀变分带,全岩矿化,成矿元素以Cu为主,伴有Au、Ag、Mo、Pd、S等多种有用组分。主要伴生元素Au、Ag、Mo在Cu和Mo精矿中能很好地富集,可产生较好的经济效益。本文通过野外地质调查、室内显微鉴定、电子探针、能谱分析、SPSS数理统计等手段,研究了伴生元素Au、Ag、Mo的赋存状态与分布规律,Au、Ag主要以类质同象或超显微包体的形式赋存于黄铜矿和黄铁矿中,Mo以独立矿物的形式赋存在辉钼矿中,Au、Ag、Mo可产于斑岩矿床的每个蚀变带的矿石中。研究成果对普朗铜矿开展矿床综合研究和矿石开发利用均具有重要意义。
Pulang porphyry copper deposit has a typical alteration zone of porphyry copper deposits,with full rock mineralization.The metallogenic elements are mainly Cu,accompanied by many useful components such as Au,Ag,Mo,Pd,and S.The main accompanying elements Au,Ag,Mo can be well enriched in Cu and Mo concentrates,which can produce good economic benefits.In this paper,through field geological survey,indoor microscopic identification,electron probe,energy spectrum analysis,SPSS mathematical statistics,etc.,the occurrence and distribution of associated elements Au,Ag,Mo are studied.Au,Ag mainly occur in chalcopyrite and pyrite in the form of isomorphic or ultra-microscopic inclusions,while Mo occurs in molybdenite in the form of independent minerals,Au,Ag and Mo can occur in ores in each alteration zone of porphyry deposits.The research results are of great significance to the comprehensive research and ore development and utilization of Pulang copper mine.
