简介 PROBLEM TO BE SOLVED : To provide a practicable method which can efficiently collect a rare metal by using a mechanochemical reaction. SOLUTION : The rare metal is obtained by bring a powder of a rare metal oxide into mechanochemical reaction with a powder of a lanthanoide element in an atmosphere of atmospheric pressure. As the powder of a lanthanoide element, cerium is preferable. As the rare metal, indium, tin, antimony, and the like can be collected. Preferably, the mechanochemical reaction is performed while mechanically performing stirring treatment. The method is also useful for collecting the rare metal from a wasted liquid-crystal panel and the like. COPYRIGHT : (C)2013, JPO&INPIT
