The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries, such as China and India. However, the content of iron ore in deposits has deteriorated and low-grade iron ore has been processed.Pelletizing - WikipediaIron ore pellets are spheres of typically 6–16 mm (0.24–0.63 in) to be used as raw material for blast furnaces. They typically contain 64–72% Fe and various additional material adjusting the chemical composition and the metallurgic properties of the pellets. Typically limestone, dolomite and olivine is added and Bentonite is used as binder.

Pelletizing - EPrints

shaft kiln. The hard pellets (about 1-1 in dia.) were thought to be a suitable blast-furnace feed material and subsequent tests in a small experimental blast-furnace were encouraging. These results attracted the attention of iron makers all over the world and inspired some par-ticularly energetic and successful work in Sweden.3,4,37 In the USA the steel and ore companies saw in this The ...Iron ore pelletization - ScienceDirect· Straight grate, grate-kiln, and shaft furnaces account for approximately 58%, 35%, and 6%, respectively, of world pellet production in 2013 (Oja, 2013).

In direct reduction, iron remains in solid state and the product is the so-called direct reduced iron (DRI). Generically, the iron ore products for ironmaking can be classified as shown in Table 1.

11.23 Taconite Ore Processing

Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material (gangue), and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.Shaft Furnace - an overview | ScienceDirect TopicsThe iron blast furnace (Fig. 47) is the most highly developed shaft furnace and can operate very efficiently not only as a heating unit but as a high temperature reaction chamber. Modern furnaces are nearly 30 m high (plus a considerable superstructure) and may be over 15 m in diameter at the hearth.Iron Ore Agglomeration Processes and their Historical ...Sintering and pelletizing are the processes of major importance for the iron production.
