A Study of the Structure and Physicochemical Properties of the Mixed Basicity Iron Ore Sinter

To study the influence of sinter basicity on microstructure, phase composition, and physicochemical metallurgical properties, samples agglomerates with different basicities were sintered investigated. A comprehensive structure, chemical, properties was conducted, optimum values for these determined. The results mineralogical transformations that occurred during sintering process are also presented. magnetite contained in concentrate partially dissolves silicate component flux agglomeration, forming a complex SFCA general formula M14O20 (M–Ca, Si, Al, Mg), which is binder ore phases agglomerate. proportion ferrosilicates calcium aluminum depends charge, morphology cooling rate sinter. more CaO formed sinter, slow growth large lamellar dendritic phases.
