Zusammenfassung:	PROBLEM TO BE SOLVED: To provide a manufacturing method of metal manganese (Mn), especially metal Mn recovered from a raw material.SOLUTION: There is provided a manufacturing method of metal Mn by mixing a reductant and flux with a Mn-containing material, inputting them to an arc melting furnace and reducing the Mn-containing material by electric heating and/or a reaction heat of the reductant. Meal Al and metal Si are preferably as the reductant, the Mn-containing material used as the raw material is the Mn-containing material by conducting a calcination treatment on manganese oxide (MnO) or manganese oxide (MnO) or manganese oxide (MnO). There is provided a method for obtaining high quality metal Mn by using the Mn-containing material obtained by reacting ozone with a leachate by leaching Mn contained in a waste dry cell, oxidizing Mn ion contained in the leachate to precipitate the same, separating the resulting Mn-containing precipitate.SELECTED DRAWING: Figure 1 【課題】金属マンガン（Mn）、特に回収された原料からの金属Ｍｎの製造方法の提供。【解決手段】Mn含有物質に、還元剤及びフラックスとを混合して、アーク溶解炉に装入し、通電加熱及び／または還元剤の反応熱により、Mn含有物質を還元する金属Ｍｎの製造方法。還元剤としては、金属Al、金属Siとすることが好ましく、原料として使用するMn含有物質は、酸化マンガン（Mn２O３）または酸化マンガン（Mn３O４）、あるいは酸化マンガン（MnO２）にか焼処理を施して得られたMn含有物質とする金属Ｍｎの製造方法。廃乾電池に含まれるMnを浸出した浸出液にオゾンを作用させて、該浸出液中に含まれるMnイオンを酸化して沈澱させ、得られたMn含有沈澱物を分離して、得られたMn含有物質を用いることにより、高品位の金属Mnを得る方法。【選択図】図１
