PROBLEM TO BE SOLVED: To securely capture, at stepped-up treatment velocity, a fine magnetic metal foreign substance 1 such as iron by separating it from a material to be treated, while avoiding restrictions on the particle diameter and the dispersion medium of a non-magnetic metal oxide to be treated such as silica or a non-magnetic hydroxide to be treated such as aluminum hydroxide. SOLUTION: A suspension 2 is obtained by dispersing a material to be treated in a dispersion medium, then is allowed to flow through the entire length of a flow path 14A of a magnetic holder 14 with a flow path 14A formed around a magnet 12, and the magnetic metal foreign substance 1 included in the suspension 2, is captured inside the flow path 14A around the magnet 12 by the magnetic force of the magnet 12. Further, the magnetic metal foreign substance 1 is separated from the material to be treated, and the suspension 2 passing through the flow path 14A is recovered/dried to obtain the material to be treated.
