Provided is a flocculation magnetic separator which reduces the used amounts of magnetic powder as well as the collected flocs thus recovered, without using a chemical such as hydrochloric acid. The flocculation magnetic separator comprises a return and addition unit (18) which returns the collected flocs discharged from a magnetic separation unit (16) to a raw water supply pipe (12) at an upstream position of a rapid stirring tank (26) and at an upstream position where a flocculant is added. This process for returning the collected flocs to the raw water supply pipe (12) enables the collected flocs to be recycled without using a chemical such as hydrochloric acid. Further, this process also enables the magnetic powder contained in the collected flocs to be recycled, resulting in the reduction of the used amounts of brand-new magnetic powder.
