To certainly segregate a component high in magnetization properties, for example, from a sintering raw material, to uniformly disperse coke over the whole of the sintering raw material and to keep good sinterability.

In this ore separator, an electric field is formed between the surface of an inclined chute 13 forming a first electrode and a second electrode 19 by a high voltage ore separating part 14 and a magnetic field is generated on the outer peripheral surface on one side of a rotary drum 15 by a magnetic ore separating part 16. By this constitution, the specific matter of a charged raw material can be sorted and/or segregated by the action of the electric field and the magnetic field.
