Arsenic-containing solution processing method |
abstract |
An arsenic-containing solution such as a high-purity and high-concentration arsenic-containing solution obtained by treating an arsenic-containing substance containing various elements other than arsenic, such as a non-ferrous smelting intermediate, Provided is a method for recovering as a powder of an iron and arsenic compound having a very low arsenic elution concentration. A divalent iron ion is added to a solution containing pentavalent arsenic of 10 g / L or more, and the molar ratio of iron to arsenic (Fe / As) in the solution is 1 or more (preferably 1-1. 5), the temperature is raised to 70 ° C. or higher (preferably 70 to 95 ° C.) with stirring by adding an oxidizing agent, and the solid content obtained by solid-liquid separation is dried.
