广西德保钦甲铜锡矿区伴生金银赋存规律研究

Study on Gold and Silver Occurrence Regularity in Qinjia Copper-Tin Ore Area,Debao Mine,Guangxi

通过对广西德保钦甲铜锡矿区伴生金银赋存规律的研究,主要金矿物为自然金、银金矿、金银矿,主要银矿物为银金矿,金银的主要载体矿物为黄铜矿、黄铁矿、毒砂,主要以间粒金、裂隙金和包裹金的形式赋存。认为在选铜的过程中,金银的载体矿物黄铁矿、毒砂被抑制,进入尾矿中,这部分矿物中的金银没有得到回收,应注重对尾矿中金银的综合回收利用;在生产探矿中,应重视对没有达到铜工业品位,但富含黄铁矿、毒砂矿物的非工业矿体进行金银品位的查定,以便发现新的金银矿体。对指导矿山找矿和提高金银的选矿回收率,均具有重要的理论和现实意义。

Based on the study of associate gold and silver occurred regularity in Qinjia copper-tin ore area,Debao Mine,guangxi,the main gold mineral are natural gold,electrum and goldargentid,the main silver mineral is electrum.The gold and silver mainly carries mineral are copper pyrite,pyrite and arsenopyrite,which mainly occurred in forms of intergranular gold,fracture gold and package gold.The author suggested that gold and silver＇s carries mineral pyrite,arsenopyrite are repressed in the course of beneficiating copper,get into tails,the gold and silver in part of this minerals didn＇t get a recall,should pay attention to the gold and silver in the tails comprehensive recall exploitation;Exploration in the production,should pay attention to don＇t attain copper production-grade,but the not-industrial ore body of rich contain pyrite and arsenopyrite,carry on checking of gold and silver grade,in order to find new gold and silver ore body,to guide ore exploration in mine and improve beneficiation recovery rates of gold and silver,all have important theory and realistic meaning.
