闪速熔炼处理高砷铜精矿的探讨
|
摘要
对"双闪"工艺处理高砷铜精矿进行了探讨,结合国内某"双闪"工厂实际生产中砷的元素分布,进行了工艺冶金计算。针对计算结果中阳极铜含砷量超标问题,提出了电收尘开路处理的解决方案,并通过某"双闪"冶炼厂的生产数据和工业试验,论证了该方法的可行性。分析结果表明,采用电收尘处理技术后,"双闪"系统中砷处理量可降低20%,产出阳极铜含砷满足要求,"双闪"工艺可有效处理高砷铜精矿。
Treatment of high arsenic copper concentrate with flash smelting was discussed.Metallurgical calculation was carried out according to arsenic distribution in one "double-flash"smelter in China.To address exceeding arsenic content in anode copper,dust recovery from electric dust collector was put forward.Feasibility of this process is demonstrated through production data and industrial test of one double-flash smelter.The results show that arsenic content can be reduced by 20% and arsenic in anode copper can meet requirement after electric dust collection."Double-flash"process can effectively treat high arsenic copper concentrate.
