Abstract
The physical structure of iron ore pellets (as determined by the technological conditions of their production) considerably affects their metallurgical properties (mainly strength and reducibility). Structural parameters of laboratory and commercial iron ore pellets were evaluated and compared using mercury porosimetry, as well as the correlation between the reducibility and the pore volume of the pellets. A closer dependence was found in the case of laboratory pellets prepared from the same iron ore concentrate. In the case of commercial pellets produced under various technological conditions, the established correlation between the reducibility and the pore volume is affected by the diversity of the phase composition and microstructure and by structural variations during reduction. Mercury porosimetry can be used for commercial pellets as an indirect controlling method to determine the reducibility of pellets.
