The study was carried out on recycling copper resources in Xinwuxia sludge by stirring and leaching method. The results of the stirring and leaching experiment indicate that using 275 spraying solution as the stirring and leaching solution, with a sludge to solution mass ratio of 1:12 and a stirring time of 5 min, provides the optimal leaching rates for copper and iron. The copper leaching rate is 80.75%, and the iron leaching rate is −29.61%. The results of the sedimentation experiment show that as the sludge to solution mass ratio decreases, the sludge sedimentation rate increases, with sedimentation essentially complete at around 250 min. Additionally, the 1:12 group with old transfer tank spraying solution has the largest sludge compression, which is conducive to solid–liquid separation.
