10.1. Physical processing for enhanced chemical and/or physical properties. Hematitic/goethitic iron ore as a bulk commodity is normally treated at its source (mine) through relatively simple physical ore dressing processes of comparatively large scale to turn it into salable products prior to transportation. The overall purpose of such treatment is twofold: In …

Australia's iron ore industry is undergoing a major transformation. Reserves of traditional high-grade ores are becoming depleted while the replacement ore types are lower in grade and sometimes require beneficiation to remove or minimise contaminants such as alumina, silica and phosphorus (Dukino et al., 2000).The phosphorus content of Australian iron ores is a …

Goethitic IO is an iron hydroxide–containing ore. During dehydration of goethitic ore at 263–370 °C, crack formation in the grains takes place because of 28.7% volume reduction due to the lattice transformation. The generated pores in the grains may cause disintegration during heat hardening of the pellets.

As the demand of iron ore is increasing, it is necessary to recover the resources from the lean grade iron ore or goethitic ores through beneficiation. The correlation of mineralogy and texture to engineering parameters such as strength, comminution efficiency, product size and liberation was attempted [2], [3], [4] .
