Magnetic　agglomeration　plays　a　vital　role　in　enhancing　the　separation　of　fine　magnetic　mineral　particles.　However,　the　forces　causing　magnetic　agglomeration　in　wet　low-intensity　magnetic　separators　(LIMS)　are　poorly　understood;　this　calls　for　improved　understanding　of　various　forces　(including　magnetic　force　(Fm),　magnetic　agglomeration　force　(Fmm),　gravity　(G))　acting　on　magnetic　particles　in　the　LIMS.　In　this　study,　a　3D　lowintensity　magnetic　field　(LIMF)　with　uniform　gradient　was　simulated,　and　the　different　forces　acting　on　magnetic　particles　were　calculated　in　the　form　of　Fmm/Fm　and　Fmm/G　by　finite　element　analysis　(FEA).　Results　show　that　magnetic　agglomeration　force　has　a　significant　competitive　effect　on　magnetic　separation.　However,　there　are　still　some　methods　to　weaken　the　effect　of　magnetic　agglomeration　force.　This　study　not　only　provides　theoretical　guidance　for　the　innovative　development　of　LIMS,　but　also　opens　a　new　perspective　for　the　recovery　of　strong　magnetic　minerals　from　ore　resources.
