Abstract
The present disclosure provides an agent for selective metal recovery, a metal recovery method, and a metal elution method.
Claims12
A method for recovering a metal or a metal compound, comprising:
- an addition step of adding a dried matter of a cell of the red algae belonging to the order Cyanidiales, a dried matter of a cell derivative of the red algae belonging to the order Cyanidiales, or an artificial matter that imitates the dried matter of the cells or the dried matter of the cell derivative to a metal solution;
- and
- an adsorption step of causing a metal or a metal compound contained in the metal solution to be adsorbed onto the cell derived from the dried matter, the cell derivative derived from the dried matter, or the artificial matter.
A metal recovery method, comprising:
- an addition step of adding a material derived from an alga belonging to the order Cyanidiales, which is dead cells or a cell surface layer of an alga belonging to the order Cyanidiales, or an artificial material produced by simulating the cell surface layer;
- and
- a recovery step of recovering a metal from the metal solution by the material derived from an alga belonging to the order Cyanidiales.
