装置。[Claims] 1. A filter element made of a ferromagnetic material is disposed in a processing fluid flow path to form a magnetic field in the flow path, and a high gradient magnetic field is formed around the ferromagnetic material. 1. A high-gradient magnetic separation device for adsorbing and removing magnetic fine particles floating in a processing fluid, characterized in that the processing fluid flow path is formed into a curved flow path. 2. The high gradient magnetic separation apparatus according to claim 1, wherein the processing fluid flow path is formed in a magnetic separation treatment tank, and the processing flow path is partitioned with a partition plate to form a bent treatment flow path. . 3. The high-gradient magnetic separation apparatus according to claim 1, wherein the ferromagnetic thin wires constituting the filter element provided in the processing fluid flow path are woven into a mesh or blind pattern. 4. The high gradient magnetic separation apparatus according to claim 1, wherein the ferromagnetic thin wire constituting the filter element provided in the processing fluid flow path is formed in the shape of glass wool. 5. The ferromagnetic thin wires constituting the filter element provided in the processing fluid flow path are made by processing a thin ferromagnetic plate by etching or punching so that the thin wire portion remains, or by adding a ferromagnetic thin plate to a non-magnetic thin plate. 2. The high gradient magnetic separation apparatus according to claim 1, wherein the high gradient magnetic separation apparatus is made of a printed material.
