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.

Control of an industrial copper solvent extraction process

The aim of the copper solvent extraction process is to concentrate aqueous copper solution from a few g/l to about 40 - 50 g/l and to purify the solution from ferrous, manganese, chloride and other impurities, which are harmful for the downstream electrowinning process. This continuous process consists of extraction and stripping processes,
