PROBLEM TO BE SOLVED: To provide a method for recovering a noble metal improved in dissolubility where, in a method in which a charged solid raw material is rotatively moved to recover a noble metal, by promoting the stirring the raw material present at the lower part of a mixer.SOLUTION: Provided is a method for recovering a noble metal improved in dissolubility where, when solid raw material obtained by applying a noble metal to the surface of a base material and a dissolution solution in which the noble metal is dissolved are charged to the drum 12 of a tilting mixer 1 so as to be rotatively driven, the charged matter is mixed and stirred to recover the noble metal, it is placed in such a manner that the tilting angle of the drum 12 of the mixer 1 reaches a fixed angle A or lower to a horizontal direction, and the stirring of the solid raw material present at the lower part of the drum 12 is promoted.SELECTED DRAWING: Figure 1 |
