Abstract
The article displays the determining infl uence of natural iron ore
mineralization on the sintering process and the strength of fl uxed sinter. Magnetite crystals with homogeneous structure actively move into the melt, forming the silicate binder ore grains in agglomerates of low basicity. With the growth of the basicity the change of silicate ligaments to ferrite ones can be determined by the amount of iron in the melt and high oxidation potential of the gas phase. The participation of magnetite of heterogeneous structure in processes of melt formation was limited. During the sintering of agglomerates the low iron content in the melt expanded the range of crystallization of silicate ligaments, shifting the start of the process of ferrite formation toward to the agglomerates of high basicity.
