Abstract

Copper is an important key metal raw material.It is of great significance to comprehensively recover and utilize copper ores containing precious metals such as gold and silver.The process mineralogy and beneficiation test of a copper sulfide ore containing gold and silver in Henan Province have been carried out.The results show that the main useful element copper content is 0.82%，the associated beneficial groups are sulfur，gold and silver，the main useful metal minerals are chalcopyrite，chalcocite，pyrite，gangue minerals are mainly quartz.The combined collector of butyl xanthoxanthate and butyl ammonium black is used in mixed flotation，the total amount of agent is 120 g/t，and the process flow of one coarse，two fine and three sweeps is adopted.The new collector TB1021 is used in copper sulfur separation flotation，and the process flow of one coarse，three fine and three sweeps is adopted.Finally，a copper concentrate with a copper grade of 15.21% and a copper recovery of 80.13%，a gold grade of 3.02 g/t，a gold recovery of 66.51%，a silver grade of 160.43 g/t and a silver recovery of 41.82%，and a sulfur concentrate with a sulfur grade of 49.13% and a recovery of 54.34% were obtained.

Key words： copper sulfide; mixed flotation; copper and sulfur separation; flotation reagent; beneficiation test; comprehensive recovery

青海柴达木发现大型金矿，可创造潜在经济价值超200亿元

“2021年以来，我们在青海省柴达木南北缘滩间山、五龙沟金矿取得了找矿重大突破，新增金资源量43.2 t，创造潜在经济价值超200亿元。”4月7日，青海省柴达木南北缘大型超大型金矿深部资源预测研究项目负责人王斌在接受中新网记者采访时表示。

素有中国“聚宝盆”之称的柴达木盆地地处青海省海西蒙古族藏族自治州，面积为25.65×104 km2，是中国重要的能源和矿产资源富集区之一。其中，位于柴达木盆地北缘的滩间山金矿和柴达木盆地南缘的五龙沟金矿是青海省柴北缘成矿带、东昆仑成矿带最具代表性的大型超大型金矿床，也是青海省集“科研—勘查—开发”为一体的示范型矿山。

据悉，柴达木盆地南北缘大规模金矿化的多期次特点与区域多期、多阶段的构造及岩浆热液活动，导致研究区金成矿规律、控矿要素等认识不足，加之研究区金矿深部定位预测研究的水平低、技术手段单一，制约了金矿深部的快速评价和找矿突破。

王斌表示，此次研究项目取得的成果是青海省在大型金矿深部首次发现了第二成矿富集空间，预示着青海省柴达木南北缘大型超大型金矿具备形成山东“焦家式”世界级金矿床的潜力，还可直接供矿山企业开发利用，保障矿山企业正常生产，带动当地民众就业。

据《中国矿产地质志·青海卷·普及本》记载，截至2017年底，青海省查明黄金资源储量481.66 t，保有资源量347.17 t。截至目前，青海省已发现金矿产地346处，最大金矿为玉树藏族自治州曲麻莱县大厂金矿，金资源量为108.63 t。
