Comminution and liberation response of iron ore types in a low-grade

Grain sizes of gangue minerals, mainly quartz, were coarser than those for iron-bearing minerals for nearly all ores. Differences in grain shapes and weak grain boundaries have led to a concentration of quartz particles in size ranges from 600 µm to 75 µm in the case of the more competent itabirite iron ores and an increase in the proportion of iron-bearing minerals in the coarse sizes.

The density, mineral nature, and the gangue of the ore affected coarse ore assimilation. During the iron ore sintering process, two types of particles are present in the sinter bed: (1) fines, which are actively taking part in melting and the formation of secondary phases, and (2) coarse ores, which are partially interacting with the surrounding melt.

The chemical composition of iron ores has an apparent wide range in chemical composition especially for Fe content and associated gangue minerals [1]. Major iron minerals associated with most of the iron ores are hematite, goethite, limonite and magnetite [1,5]. The main contaminants in iron ores are 5 E 1 6 and Al 6O 7 [1,5,7].
