| titleOfInvention | Method for processing waste copper solution/liquid to produce high copper content sludge |
| abstract | The present invention discloses a method for processing waste copper solution/liquid to produce high copper content sludge, mainly by recycling a low copper content waste solution from production of PCB in order to discharge a comparatively higher copper content sludge; first classify the waste solution into an acidic low concentration copper waste solution, an acidic high concentration copper waste solution, and an oxidized acidic high concentration copper waste liquid, and then mix with a strong alkali to react and form a cupric oxide sludge, then undergo dehydration/baking by an applicable equipment to remove water and get a comparatively higher copper content sludge; therefore, it is unnecessary to add other conversion agents to convert copper hydroxide into cupric oxide, thereby turning the valueless low copper content sludge from a waste water (or liquid) into a valuable recyclable high copper content sludge. |
