Abstract
A system for removing iron ore particles adhered by magnetic hysteresis to a magnetic matrix of a vertical magnetic separator, the vertical magnetic separator having a separation ring with a magnetic matrix; an ore feed inlet an ore accumulation vessel positioned in the lower portion of the magnetic matrix and having an outlet for low magnetic-susceptibility material; a magnetic field-generating device adapted to generate a magnetic field in the region of the accumulation vessel; at least one collection tray positioned internally to the magnetic matrix and adapted to collect material with greater magnetic susceptibility detached from the magnetic matrix; and a collecting container adapted to receive the material with greater magnetic susceptibility from at least one collecting tray. The system further includes a demagnetizer; a mechanical device for cleaning the magnetic matrix positioned at a position subsequent to the demagnetizer; and at least one device generating jets of compressed air.
