Smelting method for separating metal and inorganic particles from metal-inorganic particle composite material

摘要

A metal-inorganic particle composite material 1 is heated into a melt 2. Flux 3 is thrown into the melt 2, and both the melt 2 and the flux 3 are brought into contact with each other sufficiently. The resulting melt 2 is then left at rest so as to be separated into an upper layer containing inorganic particles 2a and a lower layer composed of metal 2b. Subsequently the upper layer and the lower layer are recovered individually.
