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 + 07 mm size, intermediate particles of − 07 + 02 mm size, and adhering particles of − 02 mm size As the .

Iron ore (fines) - Cargo Handbook - the world's largest

Description. Iron Ore (fines) Iron ores are rocks and minerals from which metallic iron can be economically extracted. The ores are usually rich in iron oxides and vary in colour from dark grey, bright yellow, deep purple, to rusty red. The iron itself is usually found in the form of magnetite (Fe 3 O 4), hematite (Fe 2 O 3), goethite (FeO(OH)), limonite (FeO(OH).n(H 2 O))
