Experimental evaluation of the usage of residues for sintermaking The shifts in quality of global reserves of iron ore as well as the progressive pelletizing allow for controlling these parameters via blending of different ores operational limits in the sinter plant gas treatment system alkali and chlorides The humid mass was then homogenized by means of two successive quarterings.
Read MoreThe iron ore in this area contains a large volume of fines (20–30% below 150 μm), which can be transformed by high moisture content into a sticky mass that is almost impossible to screen. Vale initially considered wet-process screening using water sprays to overcome the problem but ultimately rejected that approach as too costly.
Read Moreore quality is to produce ore of consistent grade (not only in iron, but also in phosphorus, silica, and alumina). Traditionally this is achieved by blending from intermediate stockpiles, but this imposes large handling and stock costs which would be avoided if the desired grade uniformity can be achieved with less rehandling of the ore.
