In this study provides an overview of chemical and physical properties of commercial iron ores as well as their influence on sintering performance. The sinter structure and its characteristics mainly depend on the raw material chemistry, phase body, crack distribution and the sintering process parameters. The aim of the studies is to present a new approach to the characterization of complex macrostructures and microstructures, especially those found in effect of sinter quality and productivity. A number of the commercial iron ores were tested in an industrial sinter plant to study the effect of iron ore composition on the sintering properties. Sintering process was performed for each individual using iron ore as constant basicity, coke dust and flux. The sintering properties of blending ores, including productivity, tumbler index (TI), suitable moisture and coke rate were approximately equal except reduction degradation index (RDI) values, to the weighted means of the individual ores. An important feature of this system is the simultaneous use of X-Ray Diffraction and Scanning Electron Microscope (SEM-EDS) which enables to determine both macro and microstructure of a sinter with high accuracy.
