high-magnesia Bakalsky concentrate (a mixture of roasted siderite concentrate and brown iron ore in equal pro-portions) in the sinter mix with the low-magnesia NMSTU iron ore concentrate. The introduction of the NMSTU concentrate into the mix was carried out in two different ways: by reducing the share of the sinter ore in the mix and
Magnetite iron ore pellets are produced by agglomerating moist, finely ground magnetite concentrate together with a binder in balling drums or balling discs to pellets, typically between 9 and 15 mm in diameter. In the Grate Kiln pelletizing process, the wet green pellets are loaded on a travelling grate with a bed height of 23 cm.
