Jun 10, 2022To avoid these problems, the authors' group developed a novel composite agglomeration process (CAP) to handle their uses in iron ore sintering [ 11 ]. In CAP, the dusts were prepared as pelletized feed, while the other raw materials including iron ore, return fines, flux, and coke breeze were used to prepare matrix feed.

Over 300 minerals contain iron but five minerals are the primary sources of iron ore. They are (i) magnetite (Fe3O4), (ii) hematite (Fe2O3), (iii) goethite (Fe2O3.H2O), (iv) siderite (FeCO3), and (v) pyrite (FeS2). The first three are of major importance because of their occurrence in large economically minable deposits.
