Iron Ore - an overview | ScienceDirect Topics
Iron ore fines are characterized on a physical basis by variations in particle size, shape, density, porosity, surface area, roughness, and wettability. Furui et al. (1977) divided iron ore particles into nucleus particles of + 0.7 mm size, intermediate particles of − 0.7 + 0.2 mm size, and adhering particles of − 0.2 mm size.

18-5-2017 · Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is produced, and thus iron agglomeration ...
