Process to remove ferric iron impurities from an acidic aqueous solution used in the electro-winning of copper |
摘要 |
A process for the removal of primarily iron impurities from acidic aqueous electrolytic solutions used in the electro-winning of copper is described. Strong base Type 1 ion exchange resin is used to remove acid from the solution resulting in a treated solution that contains only a small amount the original acid but all of the dissolved salts. This low acid treated solution is then processed using standard processes such as adjustment of the pH or oxidation potential to remove the iron impurities and the solution containing valuable process cobalt is returned to the electrolyte solution to continue the extraction of copper. |
