| description | PROBLEM TO BE SOLVED: To provide a processing method for bismuth electrolytic precipitates in which high-purity BiOCl can be produced from Bi electrolytic precipitates.SOLUTION: The bismuth electrolytic precipitate processing method includes: a step of adjusting a bismuth electrolytic precipitate to pH 1 or less with hydrochloric acid to leach; after the leaching, a step of subjecting it to solid-liquid separation; and a step of forming bismuth oxychloride by adding water so that the pH of the leached solution obtained by the solid-liquid separation exceeds 1.SELECTED DRAWING: Figure 1
【課題】 Ｂｉ電解澱物から純度の高いＢｉＯＣｌを得ることができるビスマス電解澱物の処理方法を提供する。【解決手段】 ビスマス電解澱物の処理方法は、ビスマス電解澱物を塩酸にてｐＨ１以下に調整して浸出する工程と、前記浸出後、固液分離を行う工程と、前記固液分離によって得られた浸出後液のｐＨが１を超えるように水を添加することでオキシ塩化ビスマスを生成させる工程と、を含むことを特徴とする。【選択図】 図１ |
