| titleOfInvention | Arsenic treatment in copper (Cu) electrolyte |
| abstract | In the present invention, in the preparation of arsenic acid by separating and recovering arsenic in the coin solution, a high yield of arsenic acid is prepared by using a solvent extraction and pretreatment organic solvent (Black acid) mixed with the coin solution in the preparation of the arsenic acid. According to the present invention, in treating a coin solution consisting of sulfuric acid (H 2 SO 4 ), arsenic (As) or metal ions containing arsenic, the scrubbed solution obtained in the solvent extraction process and the arsenic acid prepared liquid ( A first step of obtaining a small amount of copper concentration by mixing a portion of black acid), a second step of obtaining a TBP organic solvent from an aqueous sulfuric acid solution prepared separately, and an organic solvent obtained in a second step of a first step. A third step to obtain a stripped solution containing Raffinate, Scrubbed Solution, and Arsenic by contacting the liquefied liquid obtained in And a step of reducing the arsenic-containing back extraction solution with sulfurous acid gas (SO 2 ) and then acidifying and evaporating to extract arsenic acid (black acid) and arsenic acid. ) A technique relating to arsenic treatment in an electrolyte solution. |
