Title:
METHOD FOR RECOVERING NOBLE METAL AND COMBUSTING DEVICE
Document Type and Number:
Japanese Patent JP2009179873
Kind Code:
A
Abstract:
To provide a method for recovering noble metals by which combustion efficiency is improved to reduce energy consumption, and further the extraction rate of noble metals can be improved, and to provide a combusting device suitable for improving combustion efficiency.
The method for recovering noble metals includes: a combusting step where activated carbon with noble metals adsorbed therein is combusted to be ashed; and an extraction step where the noble metals are extracted from the ashed matter obtained by the combustion; wherein in the combusting step, the activated carbon is irradiated with microwaves to be combusted, and an oxygen-containing gas is fed to progress the combustion of the activated carbon.
