The company is also a key user of Metal Bulletin's 62% Fe Iron Ore Index (MBIOI-62) for its mid-grade products. The days of the annual "mating season" - when steelmakers and major iron ore miners would play brinkmanship over who would give way first over setting an annual iron ore price - are long over.
The limit values of the Tumble Index (TI) and Abrasion Index (AI) for the iron ore pellets used in furnace reduction process are >70 wt% for the TI value and <5 wt% for the AI value . It follows from Table 1 that the TI values of Muko ores are between 88 wt% and 93 wt%, which is significantly higher than the stipulated 70 wt%.

Iron ore pelletizing 3 Process flexibility There are two main processes for producing iron ore pellets: The Grate-Kiln system and the straight grate system. In the straight grate system, a continuous parade of grate cars moves at the same speed though the drying, induration and cooling zones. Any change in one section effects the residence
Other Asia, other Western World, and Central and Latin America will see the largest growth in iron ore pellet use for DRI or HBI. Global iron ore consumption for steelmaking could grow from 850 million tonnes at the end of the twentieth century to more than 1.3 billion tonnes over the first quarter of the twenty-first century.
Variables Affecting Pellet Properties: Pellet making is a complex process, requiring careful attention to the successive stages of feed preparation, balling, drying, firing, and cooling. Thus although the properties of the finished pellets are developed during the thermal induration or firing stage, the firing time and temperature are not the only variables which affect pellet properties.
