Definitions

  • the present invention relates to a metal recovery apparatus and more particularly, to a metal recovery apparatus for recovering metal contained in an acidic solution or the like.
  • an oxide is produced on the surface of the copper product or copper alloy product during the process. This oxide is removed by a treatment using a sulfuric acid solution and after the treatment, copper ions remain in the sulfuric acid solution.
  • the copper ion concentration of the sulfuric acid solution increases with increase in number of times of treatment and the oxide removal performance of the sulfuric acid solution is deteriorated. For this reason, the sulfuric acid solution needs to be exchanged regularly, however, this exchange increases the cost.
  • the method for recovering a copper component from the sulfuric acid solution includes crystallization, copper plate electrodeposition, barrel electrodeposition and the like.
  • Crystallization is a method of cooling a sulfuric acid solution containing copper ions to precipitate copper sulfate therefrom.
  • cooling of the solution requires much power, which increases the cost.
  • Copper plate electrodeposition is a method of immersing a copper plate as a negative plate in a sulfuric acid solution containing copper ions to deposit copper on the copper plate surface.
  • the cost of preparing the negative plate is high.
  • the negative plate to which the copper is adhered by copper precipitation is heavy, the negative plate is difficult to take out of the solution.
  • Barrel electrodeposition is a method of putting a copper chip as an electrode into a basket immersed in a sulfuric acid solution to deposit copper on the copper chip surface.
  • it is necessary to prepare a mechanism for taking the copper chip out of the basket, which increases the cost of the apparatus.
  • the documents 1 to 4 listed below also disclose methods of recovering of a copper component.
  • the document 1 discloses a technique of using as a cathode a rotating metal recovery board having a surface of Zr (zirconium) or Zr alloy, immersing a part of the metal recovery board into a treatment solution, carrying a negative current through the rotating metal recovery board to deposit powder copper on the surface by electrolysis and scraping the powder copper by the plate.
  • the document 2 disclose a technique of putting a rotating titanium metal recovery board as a cathode in acid pickling waste water containing copper, carrying a predetermined cathode current therethrough to deposit copper particles on the cathode by electrolysis and scraping the copper particles continuously for recovery.
  • the document 3 discloses a technique of putting an electrode coated with a plastic film containing carbon fine particles in a metal ion containing solution thereby to deposit metal fine particles on the surface of the film for recovery.
  • the document 4 discloses a technique of using as a cathode a copper-plated copper plate which has a surface coated with a plastic film containing carbon fine particles and is subjected to heat treatment, and recovering metal fine particles from a solution containing metal ions by electrolysis.
  • the rotating metal recovery board having a surface of Zr or Zr alloy or the titanium metal recovery board is used to deposit copper on its surface by electrolysis, the copper is adhered to the metal recovery board tightly, and therefore, scraping of the copper becomes difficult.
  • the electrodeposition plate when the electrodeposition plate is coated with a plastic film containing carbon fine particles, copper is deposited on the film surface in the form of powder, and therefore, the material deposited can be easily removed.
  • the recovery amount is less than 1 kg, for example, 210 g per 24 hours and the recovery performance is poor. Further, when the recovered powder copper is dissolved and cast, the yield rate is poor and recycling is difficult because of the powder state.
  • the present invention has an object to provide a metal recovery apparatus capable of recovering metal in a solution effectively and in such a manner that the metal is easy to recycle.
  • the present invention provides a metal recovery apparatus comprising a metal recovery board having an electrodeposition surface or conductive plate on which a metal component precipitated out of a solution is deposited and an insulator formed around the electrodeposition surface or on a part of a surface of the conductive plate.
  • a metal recovery apparatus has a metal recovery board having an insulator formed around a pattern of electrodeposition surface or a part of the conductive plate so as to deposit a metal component on an area not coated with the insulator
  • the metal component deposited on the metal recovery board can take the shape of a cluster large enough to facilitate recovery and recycling.

  • a corrosion-resistant metal of the conductive plate 2a is, for example, stainless
  • used as a material of the insulating films 2b is a resin such as fluorocarbon resin or polypropylene, which serves to prevent deposition of metal on the conductive plate 2a.
  • Forming of the insulating films 2b on the conductive plate 2a is carried out by putting the conductive plate 2a and the insulating films 2b together and heating them or bonding the conductive plate 2a and the insulating films 2b by an adhesive agent.
  • the heating temperature is determined appropriately in view of a softening temperature of the insulating films 2b or the like.
