This application relates to the field of hydrometallurgical zinc refining technology, specifically to a copper salt dechlorination recycling process for a hydrometallurgical zinc refining production line. In this process, after the zinc oxide raw material is neutrally leached to obtain a secondary leaching solution, chloride ion removal and copper salt recycling are achieved through a cyclic treatment process of "dechlorination-acid washing-alkali washing-rinsing-regeneration-copper precipitation-oxidation-copper leaching". Furthermore, an automated control system is added to the recycling process. Through real-time data acquisition and dynamic analysis of control deviations, the proportional parameters of the PI controller in the copper salt dechlorination recycling process of the secondary leaching solution are adjusted to improve the stability of dechlorination effect for different batches.
