METHOD FOR RECOVERING VALUABLE METAL, AND MAGNESIA REFRACTORY MATERIAL
To provide a method for inexpensively recovering valuable metal by using a long-life refractory material, and a long-life refractory material that is used when recovering valuable metal.SOLUTION: A method for recovering valuable metal including the following processes: a process of preparing a charging material including at least valuable metal and lithium (Li); and a process of applying oxidation treatment and reducing/melting treatment to the charging material to obtain a reduced object including molten alloy and slag, in which an object to be treated is heated in a heating furnace when performing the reducing/melting treatment, and the heating furnace has a magnesia refractory material containing a carbonaceous component.SELECTED DRAWING: Figure 2
【課題】寿命の長い耐火物を用いることで有価金属を安価に回収することができる方法、及び有価金属回収時に使用される寿命の長い耐火物を提供すること。【解決手段】有価金属を回収する方法であって、以下の工程；少なくとも有価金属及びリチウム（Ｌｉ）を含む装入物を準備する工程と、前記装入物に酸化処理及び還元熔融処理を施して、熔融合金とスラグとを含む還元物を得る工程と、を含み、前記還元熔融処理の際に被処理物を加熱炉中で加熱処理し、前記加熱炉が炭素質成分を含有するマグネシア耐火物を含む、方法。【選択図】図２
