Adsorption of antimony and arsenic from a copper electrorefining solution onto activated carbon

Removal of arsenic, antimony and bismuth impurities from copper electrolytes is a primary target in copper electrorefineries. The present work investigates the possibilities of carbon adsorption technology in the removal of arsenic and antimony from a real Chilean electrolyte. Various variables which affect the metal adsorption/desorption operations are studied. (C) 2002 Elsevier Science B.V. All rights reserved.
