titleOfInvention | Arsenic leaching recovery 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 smoke ash is made into a slurry, and an alkali is added to obtain a leaching primary leaching residue, an acid is added to the primary leaching residue to obtain a leaching secondary leaching solution, and the secondary leaching solution Neutralization was performed by adding an alkali to the obtained slurry, and a neutralized solution was obtained from the obtained slurry. After adding a neutralizing agent to the neutralized solution, an oxidizing agent was added and oxidized and leached to obtain an oxidized leach residue. And a third leaching step of adding an acid to the oxidative leaching residue to obtain an arsenic solution for producing crystalline iron arsenate as a leaching solution. [Selection] Figure 1 |
