| Abstract: | This paper has conducted the detailed experimental research on a extremely lean iron ore in Inner Mongolia, magnetic pulley preselection - rough grinding magnetic separation - rough concentarate regriding magnetic separation technology with rough grinding fineness(-200 mesh) of 73.84% and regrinding fineness(-325 mesh) of 90.57% was used, the index of concentrate yield is 8.49%, concentrate grade is 58.75% and concentrate recovery is 49.14%. The results show that this ore is extremely refractory iron ore under the existing technical conditions, th results can provide reference for future development. |
