Copper extraction from ammoniacal solutions with LIX 84 and LIX 54
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 formation of 1:1 and 1:2 co-associates. Their structures were estimated by molecular modeling.
