Copper Extraction from Ammoniacal Solutions with LIX 84

Extraction of copper from ammoniacal solutions with LIX 84 and LIX 54 used alone and their mixture was studied, and a chemical model was proposed and verified. The equilibrium extraction constant was correlated with the ionic strength. The effect is weak for the strong extractant LIX 84 and its mixture but very strong for the weak extractant LIX 54. LIX 54 acts as a modifier of LIX 84 by

Copper extraction into emulsion liquid membranes using LIX

Jan 01, 2006· Extraction of copper into ELMs with LIX 84-I at pH 5 gives a behaviour that is comparable with LIX 84 and LIX 984N-C, although the extraction rates were marginally lower. However, at pH 2, ELMs containing LIX 84-I could extract only 60% copper in 60 min of contact time in comparison with quantitative extraction of copper by ELMs containing LIX 84.

Copper—LIX 84 Extraction Equilibrium: Separation Science

Extraction of copper from water using LIX 84 extractant was investigated. Binary equilibrium data are reported and predictive models have been developed. With a simple, concentration-based equilibrium model, an equilibrium constant of 3.9 was obtained. This model is adequate when no acid is present in the aqueous phase. As the acidity of the aqueous phase increases, nonideality becomes
