Solvent extraction and electrowinning of zinc and copper

In the drawing, a leach liquor containing for example 75 g/liter copper and 25 g/liter Zn in the form of sulfates is first adjusted, if necessary, to a pH of between 0.5 and 6 and then led in stream 1 where it is contacted with copper di-(2-ethylhexyl) phosphate (Cu(DEP) 2) to extract zinc into the organic phase as Zn(DEP) 2 leaving copper sulfate in the aqueous phase.
