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.

Quartzite is a metamorphic rock consisting largely or entirely of quartz 1. In the vast majority of cases, it is a metamorphosed sandstone. Pure quartzite is grayish rock with only one dominating mineral — quartz. Width of sample 14 cm. The transition from sandstone to quartzite is gradational. There is little mineralogical change.
