MAGNETIC SORTING APPARATUS, MAGNETIC SORTING METHOD, AND METHOD FOR MANUFACTURING IRON SOURCE

WIPO Patent Application WO/2014/061256

A1

Provided are a magnetic sorting apparatus and a magnetic sorting method for efficiently separating ferromagnetic particles from a powder-particle material containing the ferromagnetic particles, and performing magnetic sorting at low cost without requiring complex steps, wastewater treatment, or the like. This magnetic sorting apparatus has: a conveyor belt for transporting a powder-particle material containing ferromagnetic particles; a rotatable hollow belt-guide roll wrapped in the conveyor belt around a portion of the outer periphery thereof; and a magnetic-field application means positioned on the inner side of the belt-guide roll, the magnetic-field application means having a plurality of magnets on the inner side of the belt-guide roll, and the ferromagnetic particles being separated in the magnetic field generated by the magnetic-field application means. The magnets are arranged so that the magnetic poles adjoining in the peripheral direction of the belt-guide roll have differing magnetism, and so that the magnetic poles adjoining in the width direction of the belt-guide roll have the same polarity.
