Method for treating mineral acid containing arsenic |
| abstract |
The present invention provides a method for treating arsenic-containing mineral acid capable of efficiently removing arsenic from a mineral acid containing dilute arsenic having an arsenic concentration of 1000 ppm or less. A method for treating arsenic-containing mineral acid that removes arsenic from a mineral acid containing dilute arsenic, wherein the arsenic-containing mineral acid is added to a sodium sulfide aqueous solution and / or in the presence of solid arsenic sulfide and / or sulfur. An aqueous sodium hydrosulfide solution is added to convert arsenic into solid arsenic sulfide, and then the solid arsenic sulfide is removed by solid-liquid separation means. [Selection figure] None |
