硝酸法处理废钨铜合金回收钨和铜新方法

A New Method of Recovery of Tungsten and Copper Metal from Tungsten-copper Alloy Scraps by Nitrate Method

对采用硝酸法从废钨铜合金中回收金属钨和铜，以及转化有害的氮氧化物的方法进行了探讨．并设计了数种较小规模的回收装置．经实验表明，本法具有操作简便、投资省、能耗低、污染小等特点，具有一定的实用价值．

A method to recever tungsten and copper metal from tungsten-copper alloyscraps by nitrate and resolve harmful oxynitrogens has been studied and obtained. Severalsmall scale retrieving devices have been designed. Experiments prove that this method iseasy to operate,saves investment and energy resources,and results in less pollution.
