Method for producing waste acid gypsum |
| abstract |
High-purity waste acid gypsum is produced at low cost. SOLUTION: A method for producing waste acid gypsum is a method in which sodium hydrosulfide is added to waste acid containing sulfuric acid generated in copper smelting, and the oxidation-reduction potential is adjusted to 20 to 150 mV (vs. SCE) to perform a sulfurization reaction. And a waste acid treatment step of removing arsenic as sulfide, and a step of producing gypsum by adding an alkali to the waste acid from which arsenic sulfide has been removed to perform a neutralization reaction.
