摘要
A method for the separation of copper and zinc during their transfer from hydrochloric acid to sulphuric acid medium using the mixed extractant Alamine 336/LIX 54 has been developed. The metal ions are extracted from hydrochloric acid medium; the extract is scrubbed in two steps in order to remove copper and chloride ions, whereby zinc passes from Alamine 336 to LIX 54. Zinc is stripped from the extract by sulphuric acid; copper is recovered from the scrubbing solution with a suitable chelating reagent (LIX 860). After conditioning with a chloride solution the mixed extractant is ready for recycling.
