摘要:
An apparatus for recovering a metal, which comprises a metal-recovering board (2) having an electrodeposition surface (2a, 2t) for the attachment of a metal component (R) precipitated from a solution and an insulating material (2b) formed around a pattern of the electrodeposition surface (2a, 2t). The metal-recovering board (2) is immersed in a metal-containing solution in an electrolytic treatment vessel (1), and thereby the metal in the solution is selectively precipitated on the electrodeposition surface (2a, 2t) and is converted to a bulk. The resultant metal bulk is scraped together for recovery with a blade (6) in a form as it is. The above apparatus for recovering a metal can be suitably used for recovering a metal in a solution in a state allowing easy reuse with good efficiency.
