✦ Synopsis

The extraction of zinc from ammoniacal/ammonium sulphate aqueous media using LIX 54 has been studied. The metal extraction rate has been examined and also the e †ect of temperature on the extraction of zinc (*H¡ \ [8É8 kJ mol~1). The e †ect of the aqueous pH, and therefore zinc ammine complex formation, on the extraction of zinc was studied. Stripping of the metal from loaded organic phases was carried out at various rates, temperatures (*H¡ \ 3É2 kJ mol~1) and sulphuric acid concentrations. The results obtained were compared with others obtained from the literature wherein di †erent extractants were used.
