ABSTRACT:
A high intensity magnetic separator conveys particles of solids suspended in a carrier medium through a magnetic field between ferromagnetic bodies and has a rotor constructed of ferromagnetic material. The rotor rotates about an approximately vertical axis and has an arrangement of containers on the outer side which holds the ferromagnetic bodies. At least one magnetic system is fixed outside of the rotor and a portion of the rotor is included in the magnetic field between the poles of the magnetic system so that the field extends through the arrangement of containers. The rotor is constructed as a hollow body and the poles of different polarity are arranged together in alignment with one another in the magnetic system. A slurry of the material to be separated is charged into each container as the same is moved into the magnetic field, middle material may be flushed out of the containers as the same rotate out of the magnetic field and the magnetic concentrate is flushed out of the containers outside of the magnetic field. Several spaced apart magnetic fields of different intensity may be employed for selective separation of materials having different susceptibility.
