Several processes based upon the direct reaction of coal and iron ore in a rotary kiln, such as the SL/RN process, have reached various stages of development since the 1960s. 20 Due to the high gangue and low specific productivity of these processes, they have not received a great deal of attention for commercial production.
Iron ore is the source of primary iron for the world's iron and steel industries. It is therefore essential for the production of steel, which in turn is essential to maintain a strong industrial base. Almost all (98%) iron ore is used in steelmaking. Iron ore is mined in about 50 countries.

· An ore is a mineral deposit that contains a metal that can be extracted using existing technological methods. Iron can be extracted from two types of iron ores: Magnetite and hematite. Magnetite is composed of iron in the form of Fe 3 O 4. Hematite is a mineral that contains iron in the form of Fe 2 O 3.
The scarcity of coking coals for blastfurnace use and the high cost of coke ovens are two reasons for the emergence of this other alternative ironmaking process. Smelting reduction employs two units: in the first, iron ore is heated and reduced by gases exiting from the second unit, which is a smeltergasifier supplied with coal and oxygen.
Iron Ore Pelletizing Equipment There are two primary types of equipment used for pelletizing iron ore: the disc pelletizer and the rotary drum agglomerator. Disc Pelletizers FEECO Disc Pelletizer, or Balling Disc Disc pelletizers, or balling discs, consist of an inclined, rotating disc mounted on a stationary structure.
1, Raymond Mill, HC series pendulum grinding mill: low investment costs, high capacity, low energy consumption, equipment stability, low noise; is the ideal equipment for wollastonite powder processing. But the degree of largescale is relatively lower compared to vertical grinding mill.
Iron Ore Crusher Iron ore crushing machine Iron ore . 12 ensp 0183 ensp Iron ore crushing The extracted iron ore will be transported to the primary crusher Over sized and wet ore will be sent to the ROM stockpile for pre treatment before it is sent to the primary crusher Primary and secondary crushing followed by screening will result in lumps and fines sized between mm .
The rotary kiln process chosen for the unit considers reduction of iron ore (520 mm) with solid carbonaceous material like coal heated up to a temperature of c in rotary kiln and then 10 cooled in a rotary cooler with external water cooling system. The products are screened and magnetically separated.
· The sintered acid iron ore does not pulverize naturally during the cooling process. It has high mechanical strength, and contains much ferric oxide (FeO), resulting in poor reducibility and bad temperature resistance. A large amount of limestone is required to smelting this kind of iron ore and concentrates. 2. Iron ore concentrates

· Iron Ore Mining Process And Machinery With Pricess. Process Overview Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or openpit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale.
· Bentonite is an effective, widely used binder in the iron ore pelletizing process. Its low price is an important factor for its extensive use. However, bentonite incorporates silica and alumina, which are undesirable contaminants to pellets. Additionally, it is a natural material with variable composition depending on its origin.
