1. A sorting device capable of separating and sorting a magnetized substance and a non-magnetized substance from a selected fluid which is a mixture of the magnetized substance and the non-magnetized substance, comprising:

  • a high-gradient magnetic separation section having;

    an electromagnet;

    a magnetic filter capable of magnetizing and demagnetizing the magnetized material by a magnetic field generated by the electromagnet; and

    a magnetic separation channel in which the electromagnet is disposed outside and the magnetic filter is disposed inside;

    a selected fluid introduction channel connected to one end side of the magnetic separation channel via a first opening/closing valve and capable of introducing the selected fluid into the magnetic separation channel;

    a first transport fluid introduction path which is connected to the one end side of the magnetic separation path via a second opening/closing valve and which is capable of introducing a first transport fluid capable of transporting the fluid to be sorted into the magnetic separation path;

    a non-magnetized material discharge passage connected to the other end side of the magnetic separation passage via a third opening/closing valve, and capable of discharging the selected fluid and the first carrier fluid in a state where the magnetized material is magnetized by the magnetic filter from the magnetic separation passage;

    a second transport fluid introduction channel which is connected to the other end side of the magnetic separation channel via a fourth opening/closing valve and which is capable of introducing a second transport fluid capable of transporting the magnetized substance in a state of being detached from the magnetic filter into the magnetic separation channel; and

    a magnetic material discharge path connected to the one end side of the magnetic separation path via a fifth opening/closing valve and capable of discharging the second transport fluid in a state where the magnetic material detached from the magnetic filter is transported from the magnetic separation path,one end side of the magnetic filter has the first on-off valve, the second on-off valve, and the fifth on-off valve,the other end side of the magnetic filter has the third opening/closing valve and the fourth opening/closing valve,the selected fluid introduction channel, the first carrier fluid introduction channel, and the magnetized material discharge channel are connected to channels on one end side of the magnetic filter, respectively.
