摘要
介绍了蚀刻液中铜的回收方法。依托某项目对酸、碱蚀刻液混合法及硫化钠沉淀法进行了工艺流程、投资和经济效益对比,结果表明:酸、碱蚀刻液混合法具有工艺简单易行、效益高和操作简便等优点,是当前首选的回收方案。
The recovery method of copper from etching solution is introduced. Relying on a project, the process flow, investment and economic benefit of acid-alkali etching solution mixing method and sodium sulfide precipitation method are compared.The results show that the acid-alkali etching solution mixing method has the advantages of simple process, high efficiency and simple operation, and is the preferred recovery scheme at present.
