Water addition, particle size distribution, ore porosity, surface properties of the iron ore and wettability of the iron ore by water are the most important factors that affect the granulation efficiency and permeability of the green sinter bed10–14. The permeability of the sinter bed in turn controls

Effects of inhaled iron oxide particles on alveolar ...

We postulated that inhaled iron oxide particles with associated amounts of soluble iron should induce mild pulmonary inflammation and lead to altered alveolar epithelial integrity and altered gas exchange. To test this hypothesis we examined the effects of inhaled iron oxide particles on alveolar epithelial permeability.
