METAL RECOVERY METHOD

摘要

PROBLEM TO BE SOLVED: To provide a metal recovery method capable of efficiently recovering metal components from the exhaust gas dust discharged from a smelting furnace in a metal refining process.

SOLUTION: The metal recovery method includes: feeding the exhaust gas dust collected through the exhaust gas flue of a first smelting furnace for metal refining to the first flue of the exhaust gas flue of a second smelting furnace for metal refining different from the first smelting furnace; and setting a gas flow rate in a second flue connected to the downstream side of the first flue lower than that in the first flue.
