METHOD FOR ELUTING AND RECOVERING METAL FROM METAL CAPTURING MEMBER

摘要

PROBLEM TO BE SOLVED: To provide a method for effectively separating and recovering captured valuable metals and harmful metals with as small generation of wastes as possible from a metal capturing member which captures the valuable metals in sea water, or captures and removes harmful heavy metals in river water and waste water. SOLUTION: The metal eluting and recovering method includes a first process to bring an eluate low in concentration into contact with a metal capturing member adsorbing metals, a second process to bring an eluate higher in concentration than that in the first process into contact with the metal capturing member to recover the intended metals in the eluate, and a third process to bring the used eluate obtained in the second process into contact with a metal re-adsorbing material to re-adsorb the intended metals.
