目前,世界各国铜电解精炼大多是采用并联法,只有美国的尼科斯厂和海登厂采用串联法(最近只剩尼科斯厂),说明老串联法已不能适应铜电解精炼技术发展的需要。但并联法和串联法亦各有其优缺点,为了改进铜电解精炼串联法,克服老串联法的缺点,利用和发展其优点,我们在现场先后进 At present, most countries in the world use electrolytic copper refining method in parallel, only the United States Nicos plant and the Hayden plant using tandem method (recently only Nikos plant), indicating that the old tandem method has been unable to meet the needs of the development of electrolytic copper refining technology. However, both the parallel method and the tandem method also have their own advantages and disadvantages. In order to improve the tandem method of copper electrolysis and to overcome the shortcomings of the old tandem method, and to utilize and develop their merits,
