摘　　要：　在红透山铜矿床区域地质、矿床地质、氧化带发育特征研究基础上,着重对氧化带内的硒矿物进行了单矿物提纯、化学分析、物理性质测定、X光衍射分析和电子探针分析。确定了含硒载体矿物的富集序列;新鉴定出含硒铜蓝;通过重液分离试验、浸取试验、电渗析分析,查明了硒的赋存状态;从氧化带剖面、矿物组合、元素组合、化学反应过程等方面,总结了硒的地球化学演化阶段;提出红透山铜矿床及其氧化带为硒的富集区;指出该区硒的资源 环境利用方向。Based on the studies of regional geology, deposit geology, oxidation zone developonent of Hongtoushan Cu deposit the Se-beaing minerals in the oxidation zone are furtherly delt with by mono-mineral purification, chemical analysis, physical test, X-ray diffraction analysis and electronic probe analysis and assemblage of Se-bearing mineral-covellite is identified. Se geochemical behavior and occurrence is summarized with heavy fluid separation, leaching and electric filtration, analysis of profile, mineral assemblage, element association and chemical evuolution. Then is put forth Se concentration zone-the oxdation zone and its resource-envionmental utilization direction.
