Solvent Extraction
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.
