| Abstract: | The average content of copper was 6.91% in a foreign refractory copper oxide ore, Using mechanical stirring-sulfuric acid leaching on the ore, the copper content was up to 30.0 g/L in the leaching solution. The process of extracting copper from sulfuric acid solution containing high copper using M5640 and kerosene was studied. The results showed that taking M5640 as extractant and using waste liquid of copper electrowinning as stripping agent, a pure copper sulphate solution which met the requirement of copper electrowinning process was obtained, performing five stage extraction and two stage stripping on conditions of suitable phase ratio. |
