Title:
金属捕集材からの金属の溶離回収及び溶離液の再生方法
Document Type and Number:
Japanese Patent JP4119966
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a method pf efficiently separating and recovering a collected useful metal or harmful metal from a metal collecting material used for collecting the useful metal from sea water or for collecting and removing the harmful metal or the like from river water or waste water with the quantity of the generation of waste as less as possible. SOLUTION: The eluting and recovering method of the metal from the metal collecting material includes a 1st process for allowing an diluted concentration eluting solution to contact with the metal collecting material, on which the metal is adsorbed, a 2nd process for recovering the desired metal in the eluting solution by allowing the eluting solution having a higher concentration than that in the 1st process to contact with the metal collecting material and a 3rd process for regenerating the spent eluting solution obtained in the 2nd process and simultaneously for further concentrating the recovered desired metal and the eluting solution regenerated in the 3rd process is used as the eluting solution in the 1st process.
