2000 A Hi Ken The copper can presumably be electroplated out of the solution with a recovery cell or removed via ionexchange But if you are looking for the simplest recovery of copper from etchant you could perhaps consider sulfuric acid peroxide etching because the copper solubility is so temperature sensitive that recovery of copper sulphate crystals is possible continuously by
