Abstract:
(EN) The present invention addresses the problem of providing an agent for selective metal recovery, a metal recovery method and a metal elution method, whereby a metal can be selectively recovered, eluted , refined, etc. at low cost and high efficiency. The agent for selective metal recovery according to the present invention is characterized by comprising a material derived from an alga belonging to the order Cyanidiales , i.e., dead cells or cell surface layer of the alga or a simulated artificial cell surface layer thereof, or porphyrin. The metal recovery method according to the present invention is characterized by comprising: an addition step for adding, to a metal solution, a material derived from an alga belonging to the order Cyanidiales , i.e., dead cells or cell surface layer of the alga or a simulated artificial cell surface layer thereof, or porphyrin; and a recovery step for recovering a metal from the metal solution with the use of the material derived from the alga or porphyrin as described above .
(FR) La présente invention aborde le problème de fourniture d’un agent pour la récupération sélective de métal, un procédé de récupération de métal et un procédé d’élution de métal, au moyen duquel a métal peut être sélectivement récupéré, élué, raffiné, etc., à un coût faible et un rendement élevé. L’agent de récupération sélective de métal selon la présente invention est caractérisé en ce qu’il comprend un matériau dérivé d’une algue appartenant à l’ordre des Cyanidiales, c’est-à-dire, des cellules mortes ou une couche de surface de cellules de l’algue ou une couche de surface de cellules artificielle simulée de celle-ci, ou une porphyrine. Le procédé de récupération de métal selon la présente invention est caractérisé en ce qu’il comprend : une étape d’ajout pour ajouter, à une solution de métal, un matériau dérivé d’une algue appartenant à l’ordre des Cyanidiales, c’est-à-dire, des cellules mortes ou une couche de surface de cellules de l’algue ou une couche de surface de cellules artificielle simulée de celle-ci, ou une porphyrine ; et une étape de récupération pour récupérer un métal à partir de la solution de métal au moyen du matériau dérivé de l’algue ou de la porphyrine tels que décrits ci-dessus.
(JA) 金属の選択的回収や溶出や精製等を低コストで効率よく行える、金属選択回収剤、金属回収方法、および、金属溶出方法を提供することを課題とする。 本発明の金属選択回収剤は、シアニディウム類の死細胞、細胞表層、もしくは、当該細胞表層を模して作製された人工物、であるシアニディウム類由来物、または、ポルフィリン、を含むことを特徴とする。本発明の金属回収方法は、シアニディウム類の死細胞、細胞表層、もしくは、当該細胞表層を模して作製された人工物、であるシアニディウム類由来物、または、ポルフィリンを、金属溶液中に添加する添加工程と、前記シアニディウム類由来物または前記ポルフィリンによって、前記金属溶液中から金属を回収する回収工程とを含むことを特徴とする。
