Abstract

It was determined through a large amount of beneficiation test to adopt stage grinding-low intensity magnetic separation-high intensity magnetic separation-reverse flotation as the principle beneficiation flowsheet for a certain hematite in Hebei. The test results indicate that we can get iron concentrate with a grade of iron 65.19% and a recovery of iron 63.17% respectively at iron concentrate 21.90%, the primary grinding of 67.54%-200 mesh and secondary grinding of 97.70%-200 mesh.
