摘    要：本文根据实验测得的数据,对湿法冶金中具有重要意义的氯化铅与氯化银结晶分离问题进行了详细的理论分析和讨论,可以预示溶液中铅、银结晶分离的可能性以及定量确定优先结晶析出氯化铅或氯化银的最佳条件。提出的分析方法原则上也适用于任何复杂体系中难溶盐的结晶分离过程。

Abstract: In this paper, based on the experimentally measured data, a theoreticalanalysis has been made for the crystallization separation of lead chlorideand silver chloride, which is of considerable importance in hydrometallur-gical practice. The possibility of the process for the crystallizationseparation of lead and silver in chloride solution can be predicted andthe optimum conditions for their selective precipitation can he determinedquantitatively. The method of analysis discussed here can be used for thecrystallization separation process of sparingly soluble salts in any othercomplex systems as well.
