摘要
探讨了粉末冶金行业用硝石熔炼法和硝酸溶解法处理硬质合金残料、废硬质合金、废钨铜合金金属钴时 ,产生的氧化氮废气的处理方法及综合利用。
The article reports studies of multipurpose utilizations of nitrogen oxide which is waste gas is the tungsten-copper alloy in nitric acid, melting the remains hard metal, waste hard metal and tungsten-copper alloy with niter and making the high pure powder cobalt.
