| titleOfInvention | High-arsenic waste acid treatment method |
| abstract | The invention discloses a high-arsenic contaminated acid treatment method which comprises the steps of sulfuric acid cinder production, acid leaching copper and zinc, neutralization and replacement reaction, arsenic recovery, zinc recovery and the like. The invention has the beneficial effects that: the invention firstly uses the high-arsenic waste acid to leach copper and zinc in the sulfuric acid cinder, utilizes the acidity of the waste acid, comprehensively extracts the copper and the zinc in the sulfuric acid cinder, reduces the copper and zinc content of the sulfuric acid cinder, improves the quality of the sulfuric acid cinder, then recovers the copper through neutralization reaction and iron powder displacement reaction, deposits the arsenic in the displaced liquid, recovers the zinc from the arsenic-deposited liquid, and returns the zinc-deposited liquid to the utilization technology, so that the acid, the copper, the arsenic and the zinc in the high-arsenic waste acid are comprehensively recovered and utilized, thereby realizing the safe treatment of the high-arsenic waste acid. |
