摘　　要：大红山铜铁矿区出露大面积前寒武系变质基底,并经历了强烈的变形和变质改造作用,似层状铜铁矿体主要产于曼岗河组和红山组的变质火山-沉积地层中。通过对大红山矿床I号矿体群中矿石和围岩(夹石)的系统测试,结果显示围岩中Au和Ag含量普遍较低,达不到伴生资源综合利用的标准。Ⅰ_(2)和Ⅰ_(3)号矿体中Au富集程度高,可以进行综合回收,6个矿体均可以达到银伴生利用的水平。Big area precambrian metamorphic base is well-exposed in Dahongshan copper-iron mine,and it has undergone intense deformation and metamorphism,near bedded copper-iron ore bodies are mainly located in metavolcanic-sedimentary strata of Mangang river formation and Hongshan formation.System testing for ore and surrounding rock(stone band)of No.I ore body cluster in Dahongshan copper-iron deposits of Yunnan has been carried out,results show that Au and Ag content is generally low,it cannot meet the comprehensive utilization standard of associated resources.The enrichment degree of Au in I_(2)and I_(3)ore bodies is high,the comprehensive recovery can be done,six ore bodies can reach the associated utilization level of silver.
