Selective Flocculation of Banded Hematite Quartzite (BHQ) Ores

banded iron ore formation (BIF)—banded hematite quartzite (BHQ), banded hematite jasper (BHJ) and banded magnetite quartzite (BMQ)—are yet to be explored due to the fine na-ture of the ore which is difficult to treat by straight-forward selective flocculation means. These low grade BIF ores con-tain 28-40% Fe and 40-55% SiO 2. The minerals ...
