1. Introduction. Blue dust is a good hematite source mineral which contains about 96% Fe 2 O 3.Since its particle size is in the range between 30 and 40 μm, it cannot be used directly in the blast furnace for iron making; however, it can be used in the form of pellets [1].Therefore, blue dust becomes a secondary source of hematite ore.

However, in most cases the Blue Dust deposits are found above the Fe-rich primary host rock known as Banded Haematite Jasper. Mineralogical observations indicate that the Blue Dust is mainly composed of haematite, martite and goethite while quartz and kaolinite are the gangue minerals. Silica removal is the primary control of iron enrichment.
