| description | The invention relates to a method for differential separation of nanometer copper powder. The method comprises the following steps of mixing nanometer copper powder to be separated with a first dispersing agent to obtain a mixed solution; carrying out centrifugal separation on the mixed solution to obtain a first precipitate and first supernatant liquid; going on to carry out centrifugal separation on the first supernatant liquid to obtain a second precipitate and second supernatant liquid, and repeating the step for N-2 times to obtain an Nth precipitate and Nth supernatant liquid; and respectively mixing the first precipitate to the Nth precipitate with a second dispersing agent, and carrying out centrifugal separation to obtain first solid to Nth solid correspondingly. The method has the advantages of being simple, convenient to carry out, economical, good in separation effect, low in copper powder loss and environmentally friendly.
