description PROBLEM TO BE SOLVED: To provide a process for producing bismuth in which a chlorine source other than chlorine gas can be used.SOLUTION: The process for producing bismuth includes: a step of subjecting a crude bismuth metal to melt-refining using chlorine; a step of casting an anode for electrolysis of bismuth obtained by said melt-refining; and a step of electrolytic winning by using said anode, and in which, characterized, in the melt-refining step, bismuth oxychloride is used as a chlorine source.SELECTED DRAWING: Figure 1 【課題】 塩素ガス以外の塩素源を用いることができるビスマスの製造方法を提供する。【解決手段】 ビスマスの製造方法は、粗ビスマスメタルに対して、塩素を用いて溶融精製する工程と、前記溶融精製によって得られたビスマス電解用のアノードを鋳造する工程と、前記アノードを用いて電解採取する工程と、を有し、前記溶融精製する工程において、塩素源としてオキシ塩化ビスマスを用いることを特徴とする。【選択図】 図１
