摘要
四川省510铀矿床伴生元素的研究多为单一矿段,为划分整个矿床的伴生资源类型,本次采用铀矿石伴生元素横向及垂向分带研究的方法,结合矿床已有的岩石地球化学、矿床地球化学、成矿规律等研究成果进行综合对比分析,梳理整个矿床伴生矿产的分带特征,将矿床在垂向上划分为铁镍硫化物—铀矿化带、少硫化物—铀矿化带和闪锌矿—少铁镍硫化物—铀矿化带3个矿物组合带,在横向上划分为上部Ni、V→Zn→Ni(少量Cu)和下部Mo、Ni、Zn、V→Zn、Ni→Mo、Ni、Zn→Zn(少量Cu)的成矿元素组合过渡带。矿床中铀与伴生钼、镍和锌等金属已完成冶炼及回收实验,增加了矿床的经济价值,扩大了经济效益。本次研究确定了510铀矿床6种伴生资源类型,对伴生元素的利用进行了综合评价,为深部找矿预测及相似矿山接替资源找矿方向提供了理论指导。
Previous studies of associated elements of the No.510 uranium deposit in Sichuan mostly focus on individual ore blocks.To classify the types of associated resources in the whole deposit,this study conducted a comprehensive comparative analysis based on the investigation of horizontal and vertical zoning of associated elements of uranium ores,as well as the existing study results of rock and deposit geochemistry and metallogenic regularity.Accordingly,this study ascertained the zoning characteristics of associated minerals in the whole deposit.In the vertical direction,the deposit was divided into three mineral assemblage zones:the iron-nickel sulfide-ura-nium mineralization zone,the low-content sulfide-uranium mineralization zone,and the sphalerite-low-content iron-nickel sulfide-urani-um mineralization zone.In the horizontal direction,the deposit was divided into the upper Ni,V→Zn→Ni(low-content Cu)and the lower Mo,Ni,Zn,V→Zn,Ni→Mo,Ni,Zn→Zn(low-content Cu)metallogenic element assemblage transition zones.The smelting and recovery experiments were completed for uranium and associated metals such as molybdenum,nickel,and zinc in the de-posit,increasing the economic value of the deposit and expanding economic benefits.This study determined six types of associated re-sources for the No.510 uranium deposit and comprehensively evaluated the utilization of associated elements,providing theoretical guidance for both the deep prospecting prediction and the prospecting of replacement resources in similar mines.
