Title:
METAL RECOVERING METHOD
Document Type and Number:
WIPO Patent Application WO/2023/286850
Kind Code:
A1
Abstract:
Provided is a metal recovering method that has a low environmental load and that can efficiently achieve recovery of metal at a low cost. A metal recovering method comprising: an adsorption step for mixing yeast with a liquid containing metal ions and causing the metal ions to be adsorbed to the yeast in the obtained mixture solution; an isolation step for isolating the yeast from the mixture solution obtained in the adsorption step; and a recover step for recovering metal ions from the yeast isolated in the isolation step, wherein the metal ions to be adsorbed to the yeast in the adsorption step are rare-earth element ions and/or noble metal ions.
