Japanese Patent JP6452790

B2

PROBLEM TO BE SOLVED: To provide a method for recovering low melting point alloy in which a low melting point alloy is recovered from a mixture (mixed liquid) of a metal microbody and a low melting point alloy to utilize.SOLUTION: Provided is a method for separating, from a mixture of a low melting point alloy that contains at least one selected from the group consisting of bismuth, tin, lead, indium, cadmium, antimony and melts at a temperature range of 16°C to 183°C and a metal body, the low melting point alloy to recover the low melting point alloy, and in which a mixed liquid of an oil, the metal body and the low melting point alloy is stirred in a state in which the temperature of the oil in a vessel is raised above the melting temperature of the low melting point alloy and heated, and then, the metal body is separated from the stirred mixed liquid by filtration, and the low melting point alloy is separated and recovered.SELECTED DRAWING: Figure 1
