Abstract

Arsenic is a harmful element that widely exists in various non-ferrous metal minerals including copper. With the depletion of free and low arsenic copper ores, containing arsenic copper ore has become an important mineral resource for copper smelting and processing. In the smelting and extraction of copper minerals, arsenic poses a serious hazard to the environment. Therefore, the safe and effective removal arsenic plays a crucial role in copper smelting and processing, and it has a great significance in promoting the green and healthy development of the copper industry. This review summarized the resource characteristics of arsenic containing copper minerals, systematically analyzed current smelting progress of containing arsenic copper minerals, and searched for the difficult and key points existed in pyrometallurgical and wet processes for containing arsenic copper mines. The reasons for difficult point formation were explored in treating arsenic containing copper minerals. The pyrometallurgical roasting followed by high-temperature filtration is documented to be an important development direction for smelting and processing of arsenic containing minerals.

含砷铜矿物除砷技术的发展与展望

摘要砷是一种有害元素，广泛存在于包括铜在内的各种有色金属矿物中。随着游离和低砷铜矿的枯竭，含砷铜矿已成为铜冶炼和加工的重要矿物资源。在铜矿物的冶炼和提取过程中，砷对环境造成了严重危害。因此，安全有效地脱砷在铜冶炼加工中起着至关重要的作用，对促进铜产业绿色健康发展具有重要意义。本综述总结了含砷铜矿物的资源特征，系统分析了当前含砷铜矿物的冶炼进展，寻找了含砷铜矿火法冶炼和湿法工艺中存在的难点和重点。探讨了含砷铜矿处理难点形成的原因。文献记载，火法冶金焙烧后高温过滤是冶炼和加工含砷矿物的一个重要发展方向。
