Recent works suggest that the use of ionic liquids in the copper solvent extraction industry is feasible. However, the reports did not use real solutions (or synthetic solutions with various elements). This fact remains poorly established, and the interaction efficiencies are still under study. The objective of this research is to explore the …

LIX ® Reagents. BASF's copper extraction reagents are based on oxime chemical structures. These reagents give up a proton (hydrogen cation) and exchange it for the Cu +2 ion. The structure of the resultant complex, called a chelate, is very specific to copper at a pH <2.5 and will reject every other metal except from a small amount of iron.
