| Abstract: | Recovery of copper from copper sludge is produced by the ammonia leaching and Ion exchange techniques. The best results were achieved when the leaching was carried out at 35~C for 50 minutes,using 12% ammonia as leaching solution,with 350 r /min stirring speed and liq- uid to residue ration 3,Cu could he effectively recovered from copper sludge by 95.9%. After the leaching solution enriched by ion-exchange resin, the concentration of recovered copper is in- creased by 20 times. And ammonia can he recycled and reused. |
