Microporosity of BIF hosted massive hematite ore, Iron . - SciELO

INTRODUCTION. For many years, iron ores were classified only by their chemical composition. In addition to the Fe2O3 content, the quality of the ore was defined by its contents of P2O5, SiO2, Al2O3, and loss on igni- tion (LOI). The steelmaking industry now requires additional data on physical properties (size-range, fines.
