PURPOSE:To recover an particulate superconducting material by cooling a raw material consisting of a particulate non-superconducting material and a particulate superconducting material to a temp. at which superconductivity is revealed, supplying the cooled raw material onto a plate magnet, and floating the particulate superconducting material from the magnet by the Meissner effect. CONSTITUTION:The raw material 1 consisting of a non-superconducting material 1A and a particulate superconducting material 1B is cooled in a cooling vessel 2 to a temp. at which the superconductivity of the material 1B is revealed. The cooled raw material 1 is supplied onto the upper part of the inclined plate magnet 5 in a cold reserving vessel 6, and the material 1B is floated from the magnet 5 by the Meissner effect. The floated material 1B is discharged into a recovery vessel 10, and recovered. As a result, only the particulate superconducting material is easily and surely selected from the raw material consisting of a particulate non-superconducting material and a particulate superconducting material. |
