For acid leaching solution of carrollite, Lix984 extractant was used to recovery copper. The effects of phase ratio, equilibrium pH, P507 volume fraction and countercurrent extraction stage on ex-traction and separation were investigated. The effects of stripping agent species and stripping ratio on the recovery rate of copper were also investigated. Experimental results showed that, with the extractant of 30% Lix984 + 70% sulfonated kerosene, the ratio of O/A of 1:1, the equilibrium pH of 2, the extraction rates of cobalt, copper, iron, after two-stage countercurrent extraction were 1.67%, 99.95% and 2.14%, respectively. The loaded organic phase after extraction was stripped with 2 mol/L sulfuric acid solution for 5 min under the stripping O/A ratio of 1:3. Under these reaction conditions, the stripping rate of copper was 100%. The loaded organic phase was stripped with 2 mol/L sulfuric acid solution and 35 g/L copper sulfate solution for 5 min under the stripping O/A ratio of 1: 3. Under these reaction conditions, the stripping rate of copper was 79.87%.
