MAGNETIC SEPARATION APPARATUS

WIPO Patent Application WO/2011/070682

A1

Disclosed is a magnetic separation apparatus comprising a vertical and annular perforated rotating container consisting of a nonmagnetic material and having the internal space sectioned into a plurality of partitioned chambers, a magnetic medium housed in each divided chamber to move freely and gravitationally, rotary drive means for rotating the perforated rotating container about the horizontal axis of rotation, a magnet which generates an effective magnetic field, a material liquid supply means for supplying material liquid to each divided chamber which reached the effective magnetic field, and a cleaning means in ineffective magnetic field for cleaning off magnetic matters adhering to the surface of the magnetic medium in the divided chamber by supplying each divided chamber which reached the ineffective magnetic field from the effective magnetic field with cleaning medium, wherein cleanability of the magnetic medium to which magnetic matters are adhering is improved and collectability of magnetic matters from the material liquid is also improved.
