Separation of hematite from banded hematite jasper

The separation of iron oxide from banded hematite jasper (BHJ) assaying 47.8% Fe, 25.6% SiO 2 and 2.30%Al 2 O 3 using selective magnetic coating was studied. Characterization studies of the low grade ore indicate that besides hematite and goethite, jasper, a microcrystalline form of quartzite, is the major impurity associated with this ore.

Reverse flotation separation of hematite from quartz

The effect of magnetite as a magnetic seed on the flotation separation of fine hematite and quartz was studied by reverse micro-flotation and sedimentation. The results demonstrate that fine magnetite could selectively report to the pulp product with hematite particles, forming aggregates that avoided attachment to quartz particle surfaces.
