| titleOfInvention | Method for separating arsenic and iron from arsenic-containing iron slag |
| abstract | The invention provides a method for separating arsenic and iron from arsenic-containing iron slag, and relates to the field of hydrometallurgy. A method for separating arsenic and iron from arsenic-containing iron slag, comprising: mixing raw materials including arsenic-containing iron slag and sulfuric acid to obtain a first mixed solution, and performing a first solid-liquid separation after the first reaction to obtain a first filtrate; The materials in the first filtrate and sodium sulfide are mixed to obtain the second mixed solution, and the second solid-liquid separation is carried out after the second reaction to obtain the second filtrate and arsenic sulfide slag; The materials are mixed, an alkaline substance is added after the third reaction to obtain a third mixed solution, and a third solid-liquid separation is performed after the fourth reaction to obtain a third filtrate and iron-removing slag. The method for separating arsenic and iron from arsenic-containing iron slag provided by the present application has the advantages of low treatment cost, good arsenic and iron separation effect, and is beneficial to the environmental protection treatment of arsenic. |
