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.

含砷铜矿脱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。随着游离砷和低砷铜矿石的枯竭，含砷铜矿石已成为铜冶炼和加工的重要矿产资源。在铜矿物的冶炼和提取过程中，砷对环境造成严重危害。因此，安全有效的脱砷在铜冶炼加工中起着至关重要的作用，对于促进铜工业绿色健康发展具有重要意义。本文综述了含砷铜矿资源特征，系统分析了目前含砷铜矿冶炼进展，查找了含砷铜矿火法冶炼和湿法冶炼工艺中存在的难点和关键点。探讨了处理含砷铜矿物时难点形成的原因。火法焙烧高温过滤被认为是含砷矿物冶炼加工的重要发展方向。
