Title (EN) PROCESS FOR RECOVERY OF METALS AND EQUIPMENT THEREFOR
(FR) PROCÉDÉ DE RÉCUPÉRATION DE MÉTAUX ET ÉQUIPEMENT IDOINE
(JA) 金属の回収方法とその装置
Abstract:
(EN) The invention relates to a process for recovering heavy metals such as nickel (Ni), copper (Cu), tin (Sn), indium (In), and gallium (Ga) as valuable simple substances or alloys from a raw effluent (such as wastewater) containing them and equipment for the recovery and aims at providing a process for recovery by which only objective metals can be recovered as valuable simple substances or alloys little containing impurity metals from a raw effluent such as wastewater with high recovery and at high purity; and equipment for the recovery. The process is characterized by incorporating a raw effluent containing objective metals in the form of ions with a precipitating metal having an ionization tendency higher than those of the objective metals, making the objective metals contained in the raw effluent deposit on the surface of the precipitating metal by utilizing the difference between both in ionization tendency, and then scaling the objective metals from the precipitating metal by a scaling means to recover them.
(FR) L’invention concerne un procédé de récupération des métaux lourds comme le nickel (Ni), le cuivre (Cu), l’étain (Sn), l’indium (In), et le gallium (Ga) comme substances précieuses simples ou alliages à partir d’un effluent brut (comme des eaux usées) les contenant et un équipement de récupération. Le procédé de récupération permet de récupérer uniquement des métaux cibles comme substances précieuses simples ou alliages contenant peu de métaux d’impureté à partir d’un effluent brut comme des eaux usées avec un rendement de récupération élevé et l'obtention d'une grande pureté. Le procédé est caractérisé en ce qu’il incorpore un effluent brut contenant des métaux cibles sous forme d’ions avec un métal de précipitation ayant une tendance à l’ionisation supérieure à celle des métaux cibles, conduisant les métaux cibles contenus dans l’effluent brut à se déposer sur la surface du métal en précipitation en utilisant la différence entre les deux en matière de tendance à l’ionisation, avant décalaminage des métaux cibles à partir du métal en précipitation à l’aide d’un moyen de décalaminage afin de les récupérer.
(JA)  Ni(ニッケル)、Cu(銅)、Sn(錫)、In(インジウム)、Ga(ガリウム)等の重金属を含む廃液等の被処理液から、それらを有価物である金属単体あるいは合金として回収する方法と装置に関し、廃液等の被処理液から目的とする金属のみを有価物である金属単体あるいは合金として回収することができ、且つ回収対象金属以外の不純物を含有する可能性が少なく、回収率が高く回収対象金属の純度が高い回収方法と装置を提供することを課題とする。  回収対象金属がイオン状態で含有されている被処理液に、前記回収対象金属よりもイオン化傾向が大きい析出用金属を添加し、イオン化傾向の差異により前記被処理液中に含有される回収対象金属を前記析出用金属の表面に析出させ、その後、剥離手段によって前記析出用金属から前記回収対象金属を剥離して回収することを特徴とする。
