由于废弃物的成分不同，二次资源的回收过程通常会遇到问题。为提高传统湿法冶金工艺对二次资源的适用性，需要对工艺组分进行调整。在传统的湿法冶金分离中，沉淀和络合被广泛使用。然而，它们的组合作为特定的金属分离方法尚未被详细研究。这种方法对于解决二次资源回收过程中组分变化引起的问题是非常有前途的。综述了沉淀和络合在金属分离过程中的作用，介绍了为调整二次资源组分而开发的“络合-沉淀”金属分离方法体系。
Recovery processes of secondary resources usually encounter problems because of the diverse compositions of wastes. To enhance the applicability of traditional hydrometallurgical process toward secondary resources, the adjustment of components is necessary. In traditional hydrometallurgical separation, precipitation and complexation are extensively used. However, their combination as a specific metal separation method has not yet been studied in detail. This approach is very promising for solving problems caused by changeable components during recycling processes of secondary resources. This paper reviews the effects of precipitation and complexation in metal separation processes, and a metal separation method system of "complexation-precipitation" developed to adjust the components of secondary resources is introduced.
