flotation of hematite ore

Magnetic and flotation studies of banded hematite ...

Dec 16, 2010· The BHQ ore was assayed as 38.9wt% Fe, 42.5wt% SiO 2, and 1.0wt% Al 2 O 3. In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in small amounts. The liberation of hematite particles can be enhanced to about 82% by reducing the particle size to below 63 μm.
