| titleOfInvention | Arsenic leaching method from non-ferrous smelting ash |
| abstract | [PROBLEMS] To recover most arsenic as a pentavalent arsenic solution without using a sulfurizing agent when recovering arsenic from non-ferrous smelting ash, and to prevent copper from being mixed into the arsenic solution. It is to provide a method for leaching arsenic from smelted ash. The non-ferrous smelting ash is made into a slurry, sulfuric acid is added to the slurry to perform primary leaching, and water and / or a neutralizing agent is added to the slurry after completion of the primary leaching step to obtain a pH value. A non-ferrous smelting ash having a step of performing oxidative leaching by adding an oxidant after adjustment, obtaining a second leaching residue of the obtained oxidative leaching, and obtaining an arsenic solution for producing crystalline iron arsenate as a secondary leaching solution Provides a method for leaching arsenic from [Selection] Figure 1 |
