BIF I is represented by magnetite and chert with little martite, hematite and goethite. Occa- sional presence of pyrite is observed. It has undergone metamorphism in moderate to high temperature and pres- sure conditions. BIF II is mostly martitised magnetite and quartz. Martite is a variety of hematite pseudomorph after magnetite.

tion. According to the mineralogy and texture the ore could be classified in four types (coarse hematite, mi-croplaty hematite, limonite and martite) with different reduction characteristics. Limonite and martite showed better reducibility than coarse and fine hematite. At all ore types the growth of dense magnetite rims was observed.
