To provide a method for recovering a low melting point metal by using the difference of a melting point, which recovers the low melting point metal of a useful metal like zinc as dust containing much metal by using the difference of the melting point, while preventing the possibility of synthesizing a hazardous material such as dioxin.

This recovering method comprises passing a gas containing the low melting point metal through the 1st filtering unit 3, while keeping the gas in a higher temperature than the melting point of the low melting point metal; then cooling the gas to a temperature lower than the melting point of the low melting point metal; and introducing the gas into the 2nd filtering unit 4 to recover the low melting point metal therein.
