Copper was extracted from ammoniacal-ammonium sulfate solutions into ELMs using LIX 84 I as carrier. Although earlier investigators have preferred using LIX 54 (β-diketone) as carrier for removal of metals from ammoniacal solutions, it is found that the ketoxime LIX 84 I could be effectively used for copper extraction at pH range 8.1 to 9.0.

The recovery of copper from ammoniacal medium using non-dispersive solvent extraction (NDSX) with hollow fibres as contactors was studied. The β-diketone LIX 54 was used as an extractant. The influence of the flow rates, initial concentration of copper in the aqueous feed phase and concentration of extractant on the extraction rate was …

Abstract This paper reports a study of the extraction of copper from ammonia/ammonium sulfate medium with LIX 54, a β‐diketone. The extraction of copper is very sensitive to the equilibrium pH. The highest extraction efficiency is attained in the range of pH 8–9.5. Above pH 10, the percentage of metal ion extracted decreases sharply. The extraction of copper …

The pure active constituent of LIX 54, manufactured by Henkel Co. as an extractant for copper from ammoniacal aqueous solutions, has been isolated. Structural investigations using elemental analysis and spectroscopic techniques (1H-NMR, IR, MS) support the belief that this reagent is 1-phenyl-1,3-decanedione. The keto-enol tautomerism of the reagent …

LIX 54 or LIX 54-100 as presently re-named, was obtained from Henkel, being used as received by diluting it to the desired concentration in Iberfluid. The active substance is a β-diketone whose composition has been reported to be based on six isomeric 1-phenyldecane-1,3-diones, heptane-8,10-dione and 1,3-diphenylpropane-1,3-dione [13] .

The main difference between the two carriers was the extraction rate, which was higher for LIX 84-I. This behaviour was due to the different extraction abilities of these reagents, with LIX 84-I acting as a stronger extractant than LIX 54, as shown in the distribution data presented in Table 3.Nevertheless, the recoveries of copper were …
