Zusammenfassung:The invention relates to the technical field of hydrometallurgy, in particular to a regeneration method of a CP180 copper extraction agent. According to the method, ammonium hydroxide or ammonium bicarbonate is adopted to replace traditional scrubbing solutions to wash, regenerate and reuse poisoned CP180, so that the reuse effect of CP180 is not changed, and the problem that CP180 is easy to be poisoned and aged when Ge, Cu and Zn organic phases are separated and extracted from a H2SO4 solution containing Ge, Cu and Zn is solved; the smooth implementation of the process that CP180 is reused for extracting copper is facilitated, so that the usage amount of CP180 is reduced, and the discharged volume of waste liquor and environmental pollution are reduced; the phase-splitting in the washing process is easy, the difficulty of the regeneration, recycle and treatment of CP180 is reduced; the cost of the regeneration of CP180 is reduced; the cost of purifying Ge and Cu when a solution containing Zn is electrolyzed to generate Zn is reduced.
