Open Access Selective Flocculation of Banded Hematite,
Fe with 71% recovery. The overall results indicate that separation of very fine grained hematite present in the BHQ iron ore is feasible by selective flocculation. Keywords: BHQ ore, Selective flocculation, Potato starch, XRD, FTIR, SEM. INTRODUCTION SelectiveUnderground Mine Mapping -- Mining Methods - Minnesota DNR,,Underground mining of natural iron ore deposits occurred on the Mesabi Range in northeastern Minnesota from 1892 to 1961. The Mesabi Range is the ledge rock exposure of the Biwabik Iron Formation, a geological feature that stretches in length for just over 100 miles, from west ofbeneficiation of ilmenite by selective leaching,beneficiation of ilmenite by selective leaching.
