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.nThe 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 . |
