  • Magnetic and flotation studies of banded hematite ...

    Dec 16, 2010  To identify and establish beneficiation techniques for banded hematite quartzite (BHQ) iron ore, a comprehensive research on BHQ ore treatment was carried out. The BHQ ore was assayed as 38.9wt% Fe, 42.5wt% SiO2, and 1.0wt% Al2O3. In this ore, hematite and quartz are present as the major mineral phases where goethite, martite, and magnetite are present in small amounts.

    India does not have enough high-grade hematite ores but has abundant resources of low-grade iron ores such as banded hematite quartzite/Jasper (BHQ, BHJ) and banded magnetite quartzite (BMQ). Indian hematite deposits belong to the Precambrian iron ore series and the ore occurs as banded, laminated, friable and also in powder form.

  • Reverse flotation separation of hematite from quartz ...

    Aug 01, 2019  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.
