The extraction–stripping reaction of Cu(II) by Lix‐84 in kerosene from aqueous sulphate medium of pH 2·5 has been investigated. The effects of pH, metal ion, extractant and strip solution concentrations as well as the loading capacity of the extractant were investigated. The number of stages required for the extraction and stripping of copper was also evaluated. The results are used to assess the conditions for purification of industrial waste solutions containing copper through counter‐current extraction in a horizontal mixer‐settler.
