Ore Sintering - an overview | ScienceDirect Topics

The “ore group” iron ore textural classification scheme (Table 2.7 and Figures 2.7 and 2.8) has been developed to link ore texture to downstream processing performance including lump/fines ratio, beneficiation, blast furnace lump physical and metallurgical properties, or fine ore sintering quality (Clout, 2002). The Ore Group scheme defines textural groupings on the basis of similarities in mineralogy, ore texture, porosity, mineral associations, and hardness.
