| description | PROBLEM TO BE SOLVED: To provide an extraction method for stably dispersing metal particulates into a nonaqueous solvent, to provide a nonaqueous solvent dispersion liquid in which metal particulates are stably dispersed, and to provide its application. SOLUTION: In the method where, from a metal particulate-water dispersion liquid comprising metal particulates and a compound (an aqueous dispersant) having affinity to water, the metal particulates are extracted into a nonaqueous solvent, using a nonaqueous solvent which allows the aqueous dispersant to depart from the metal particulates and further phase-separated from water, the metal particulate-water dispersion liquid, the nonaqueous solvent, and a compound (nonaqueous dispersant) having affinity to the metal particulates and the nonaqueous solvent are mixed, then, the metal particulates are transited to the nonaqueous solvent, and the nonaqueous solvent layer in which the metal particulates are dispersed is separated from the water layer.
