Microporosity of BIF hosted massive hematite ore, Iron

Abstract Massive hematite ore (MHO) is a special high-grade iron ore, used as lump ore in the process of obtaining direct reduction iron (DRI).The influence of porosity on the reducibility of MHO from the Capito do Mato Mine (Iron Quadrangle, Brazil) was investigated using optical and scanning electron microscopes on drill core and open pit samples.
