| 摘 要： | 高砷铜矿是一类重要的铜资源,砷含量高,通过物理分选方法无法实现高效脱砷。目前,湿法脱砷是一种高砷铜矿脱砷的重要手段。本文主要阐述了高砷铜矿砷脱除的湿法工艺,包括酸浸脱砷、碱浸脱砷、细菌脱砷,并对三种湿法脱砷工艺的原理和优缺点进行了总结。此外,对高砷铜矿浸出后的含砷浸出液,分析了化学沉淀法、电化学处理、吸附法、生物法等固砷方法,指出了对应固砷方法的原理、适用范围及其优缺点。最后,总结分析了湿法脱砷及固砷方法的问题,并对脱砷方法进行了展望。

| Abstract: | High arsenic copper ore is an important class of copper resources with high arsenic content, which cannot be efficiently removed by physical sorting methods. At present, wet arsenic removal is an important means of arsenic removal from high arsenic copper ore. This paper mainly describes the wet process of arsenic removal from high arsenic copper ore, including acid leaching arsenic, alkali leaching arsenic and bacterial arsenic removal, and summarizes the principles, advantages and disadvantages of the three wet arsenic removal processes. In addition, the arsenic-containing leachate after leaching of high arsenic copper ore was analyzed by chemical precipitation method, electrochemical treatment, adsorption method, biological method and other arsenic fixing methods, and the principles, scope of application and advantages and disadvantages of the corresponding arsenic fixing method were pointed out. Finally, the problems of wet arsenic removal and arsenic fixation methods are summarized and analyzed, and the arsenic removal methods are prospected. |
