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.
