Description
本発明は、金を含有する溶液から金を電解回収するための装置に係り、特に円筒状陰極表面に電着した金を陰極から容易に剥離することができるようにした金の電解回収装置に関するものである。 The present invention relates to an apparatus for electrolytically recovering gold from a solution containing gold, and more particularly to an apparatus for electrolytically recovering gold that can easily separate gold deposited on the surface of a cylindrical cathode from the cathode. Is.
金めっき液、電子部品等をリサイクル処理した際に発生する金を含有する廃液から金を回収する手段として、電解法が広く実施されている。
金めっき廃液等の金を含有する溶液から金を電解回収する装置として、例えばＴｉ製回転陰極を使用して金めっき廃液及び金めっき後の洗浄水から金を電解回収する装置が開示されている。この装置では、電着金の剥離脱落防止する方法としてＴｉ回転電極の表裏面を弗化水素酸または塩酸或いは硝弗酸で酸化膜を除去することを特徴とするものである。
（例えば、特許文献１参照）
As a means for recovering gold from waste liquid containing gold generated when a gold plating solution, electronic parts, etc. are recycled, an electrolysis method is widely implemented.
As an apparatus for electrolytically recovering gold from a solution containing gold such as a gold plating waste liquid, an apparatus for electrolytically recovering gold from a gold plating waste liquid and cleaning water after gold plating using, for example, a Ti rotating cathode is disclosed. . This apparatus is characterized in that the oxide film is removed with hydrofluoric acid, hydrochloric acid or nitric hydrofluoric acid on the front and back surfaces of the Ti rotating electrode as a method for preventing the electrodeposition gold from peeling off.
(For example, see Patent Document 1)
また、金等の有価金属を含有するシアン廃液を電解槽に供給し、陽極に不溶性材料を用いると共に、陰極板を回転させながら電気分解を行い、該陰極板表面に金等の有価金属を析出させるシアン含有廃液からの有価金属の回収装置が知られている。（例えば、特許文献２参照） In addition, cyan waste solution containing valuable metals such as gold is supplied to the electrolytic cell, and insoluble materials are used for the anode, and electrolysis is performed while rotating the cathode plate to deposit valuable metals such as gold on the surface of the cathode plate. An apparatus for recovering valuable metals from a cyan-containing waste liquid is known. (For example, see Patent Document 2)
そしてまた、金同様に銀を含有する溶液から銀を電解回収する装置として、例えば、電解槽、この電解槽内に配置された陽極、この陽極を包囲して前記電解槽内に配置された取り外し可能な陰極、および前記陰極および陽極のための、前記電解槽の外側に設けられた電気接続具を備え、前記電解槽は導電性の接触面を有し、前記陰極の変形可能な部分を前記接触面に対して把持して陰極の接続具から陰極への電気的接続を行う把持装置を備えた銀の回収装置が知られている。（例えば、特許文献３参照） And, as an apparatus for electrolytically recovering silver from a solution containing silver like gold, for example, an electrolytic cell, an anode disposed in the electrolytic cell, and a removal surrounding the anode and disposed in the electrolytic cell Possible cathodes and electrical connections for the cathodes and anodes provided outside the cell, the cell having a conductive contact surface, the deformable part of the cathode being 2. Description of the Related Art A silver recovery device is known that includes a gripping device that grips a contact surface and electrically connects a cathode connector to a cathode. (For example, see Patent Document 3)
しかしながら、特許文献１の貴金属電解回収装置は、Ｔｉ回転電極へ剥離脱落せずに密着するものと考えられるが、前記のＴｉ回転電極へ電着した金は、電極の表面全体に亘って上端から下端までびっしりと、付着されているのでＴｉ回転電極を再使用するためＴｉ回転電極から金を剥すのにヘラやハンマーを使用しても容易に剥離することができないという問題点があった。 However, the precious metal electrolysis recovery device of Patent Document 1 is considered to adhere to the Ti rotating electrode without peeling off, but the gold electrodeposited on the Ti rotating electrode is from the upper end over the entire surface of the electrode. Since the Ti rotating electrode is reused because it is tightly attached to the lower end, there is a problem that even if a spatula or a hammer is used to peel gold from the Ti rotating electrode, it cannot be easily peeled off.
また、上記特許文献２に開示された有価金属回収装置は陰極として円筒形状のものを使用するのではなく円板状のものを使用する点で本願発明の電解回収装置と相違する。
上記の円板状陰極は表面、裏面の両方へ金、銀等の貴金属が厚く電着されるため陰極から貴金属を剥すのにヘラやハンマーを使用しても容易に剥離することができないという問題点があった。
Further, the valuable metal recovery device disclosed in Patent Document 2 is different from the electrolytic recovery device of the present invention in that it uses a disc-like one instead of a cylindrical one as a cathode.
The above disk-shaped cathode has a problem that noble metals such as gold and silver are thickly electrodeposited on both the front and back surfaces, so that even if a spatula or hammer is used to peel the noble metal from the cathode, it cannot be easily peeled off. There was a point.
上記した特許文献３開示されているような円筒形状の陰極を使用する電解回収装置においては、陰極材料そのものが薄く、上縁には多数の切込みが設けられているので電解槽への装着、取外等の作業にたいへん手間が掛かった。
また、析出した銀が陰極より剥離する場合があり、それにより陽極と陰極とが短絡し、陽極の消耗が促進され、電解の継続に支障をきたすものであった。
In the electrolytic recovery apparatus using a cylindrical cathode as disclosed in Patent Document 3 described above, the cathode material itself is thin, and a large number of cuts are provided on the upper edge. It took a lot of work to work outside.
Further, the precipitated silver may be peeled off from the cathode, whereby the anode and the cathode are short-circuited, the consumption of the anode is promoted, and the continuation of electrolysis is hindered.
本発明は、ステンレス、チタン等の円筒状回転陰極を使用した金の電解回収装置において、円筒状回転陰極を繰返し再使用し得るようにするべく、陰極に電着した金を容易に剥離することができるように改良した金の電解回収装置を提供することを目的とする。 The present invention provides a gold electrowinning recovery apparatus using a cylindrical rotating cathode such as stainless steel or titanium, in which the electrodeposited gold is easily peeled off so that the cylindrical rotating cathode can be reused repeatedly. It is an object of the present invention to provide a gold electrolytic recovery apparatus improved so as to be capable of achieving the above.

Further, the cylindrical cathode after peeling and collecting the gold can be reused repeatedly.
以下、本発明について図面に従ってさらに詳細に説明する。
図１は本発明に係る金の電解回収装置の斜視図である。
図１に示すように、電解槽１は、制御装置２が一体となっていて、この制御装置２によって電流制御が行われている。電解槽１の内部中央部には、円筒状陰極３が陰極固定棒１０によって回転するようにネジ１３によって固定されている。この円筒状陰極３は金の析出が済んだ後、ネジ１３を外すことにより電解槽１から容易に取り外しすることができる。また、円筒状陰極３の外周には、陽極４が相対するように設置されている。
Hereinafter, the present invention will be described in more detail with reference to the drawings.
FIG. 1 is a perspective view of a gold electrolytic recovery apparatus according to the present invention.
As shown in FIG. 1, the electrolytic cell 1 is integrated with a control device 2, and current control is performed by the control device 2. A cylindrical cathode 3 is fixed to the inner central portion of the electrolytic cell 1 by screws 13 so as to be rotated by a cathode fixing rod 10. The cylindrical cathode 3 can be easily removed from the electrolytic cell 1 by removing the screw 13 after gold is deposited. Further, the anode 4 is installed on the outer periphery of the cylindrical cathode 3 so as to face each other.

帯状絶縁材６の間隙を空けずに連続して装着しておいた場合、析出した金は、帯状絶縁材６を境にして陰極から剥離し、電解の途中で脱落しまうため間隙８を設けておくことが重要である。
On the other hand, a strip-shaped insulating material 6 is fixed at one longitudinal position of the outer peripheral surface 5 of the cylindrical cathode 3 with screws 9 so that a plurality of gaps 8 can be attached and detached.
When the belt-like insulating material 6 is continuously mounted without leaving a gap, the deposited gold peels off from the cathode at the border of the belt-like insulating material 6 and falls off during the electrolysis, so that a gap 8 is provided. It is important to keep
