Apparatus For Recovery Metal

Abstract

An apparatus for recovering a metal, which comprises a metal-recovering board ( 2 ) having an electrodeposition surface ( 2 a, 2 t ) for the attachment of a metal component (R) precipitated from a solution and an insulating material ( 2 b ) formed around a pattern of the electrodeposition surface ( 2 a, 2 t ). 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 ( 2 a, 2 t ) 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.

1 . A metal recovery apparatus comprising: a metal recovery board having an electrodeposition surface to which a metal component precipitated from a solution is attached and an insulator formed around the electrodeposition surface. 
     
     
         2 . The metal recovery apparatus of  claim 1 , wherein the electrodeposition surface is a surface of a conductive plate and the insulator is formed on a part of the surface of the conductive plate. 
     
     
         3 . The metal recovery apparatus of  claim 1  or  2 , wherein the electrodeposition surface is a cathode for precipitating the metal component from the solution by electrolysis. 
     
     
         4 . The metal recovery apparatus of any one of  claims 1  to  3 , wherein the electrodeposition surface is attached rotatably. 
     
     
         5 . The metal recovery apparatus of any one of  claims 1  to  4 , wherein the insulator has a slit formed for exposing the electrodeposition surface. 
     
     
         6 . The metal recovery apparatus of  claim 5 , wherein the electrodeposition surface is circular and the slit is shaped like a plurality of concentric circles. 
     
     
         7 . The metal recovery apparatus of  claim 5 , wherein the slit is shaped like rectangles extending radially on the electrodeposition surface. 
     
     
         8 . The metal recovery apparatus of any one of  claims 1  to  7 , wherein at least one part of the electrodeposition surface has a protuberant portion and the insulator is formed around the protuberant portion. 
     
     
         9 . The metal recovery apparatus of any one of  claims 1  to  8 , wherein the insulator is made of a resin. 
     
     
         10 . The metal recovery apparatus of any one of  claims 1  to  9 , further comprising a scraper blade for scraping a cluster of the metal component deposited on the electrodeposition surface. 
     
     
         11 . The metal recovery apparatus of any one of  claims 1  to  10 , wherein the metal component is copper or copper alloy and the solution is an acid pickling solution.
