To provide a magnetic separation device and a magnetic separation method which is configured so as to permit improvement of magnetic separation operation efficiency by fitting a number of sheets of magnetic filters into an annular cable body and endlessly moving the magnetic filters.SOLUTION: A magnetic separation device includes: a superconductive magnet 3 having a bore 3a; a flow pipe 4 which is penetrated and arranged into the bore 3a of the superconductive magnet 3 and causes slurry containing substances to be separated that applies magnetism to flow therethrough; a number of sheets of magnetic filters 5 which can adsorb the substances to be separated in the slurry within the flow pipe 4; and a filter movement mechanism 6 which moves the magnetic filters 5 to the inside and outside of the flow pipe 4. The filter movement mechanism 6 includes an annular cable body 7 which fits the magnetic filters 5 at an interval, passes from the inside of the flow pipe 4 through the outside thereof and again returns to the inside thereof; and a posture retention means 8 which retains a magnetic filter 5 in such a posture as to face a slurry flowing direction in the flow pipe 4.SELECTED DRAWING: Figure 1 【課題】 多数枚の磁気フィルタを環状の索条体に装着してエンドレス状に移動させて、磁気分離作業効率を向上できるようにする。【解決手段】 ボア３ａを有する超伝導磁石３と、この超伝導磁石３のボア３ａ内に貫通配置されていて磁性付与の被分離物質を含有する泥水を流動させる流動管４と、この流動管４内で泥水中の被分離物質を吸着可能な多数枚の磁気フィルタ５と、この磁気フィルタ５を流動管４内外に移動させるフィルタ移動機構６とを備えている。前記フィルタ移動機構６は、磁気フィルタ５を間隔をおいて装着しかつ流動管４の内側から外側を通って再び内側に戻る環状の索条体７と、流動管４内において磁気フィルタ５を泥水流動方向に対面する姿勢に保持する姿勢保持手段８とを有する。【選択図】図１
