In addition, large amounts of tailings were produced in the beneficiation process of lowgrade iron ore, which has caused severe environmental problems, such as land occupation, reclamation, and water pollution [23,24,25]. Thus, it is essential to develop novel technologies to achieve the comprehensive utilization of lowgrade iron ore resources.

Beneficiation is the process where ore is reduced in size and gange separated from the ore. Since all iron ore deposits have unique mineralogy, the beneficiation process is specific to each deposit. Separation of certain minerals can be efficiently achieved by taking advantage of the physical, electrical and magnetic properties.

The iron ore production has significantly expanded in recent years, owing to increasing steel demands in developing countries. However, the content of iron in ore deposits has deteriorated and lowgrade iron ore has been processed. The fines resulting from the concentration process must be agglomerated for use in iron and steelmaking. This chapter shows the status of the pelletizing process ...

Conventionally iron and steel is produced by the reduction of highgrade iron ores in a blast furnace. About 80% of the world's iron making is achieved through the blast furnace process and rest by different direct reduction (DR) processes. The role of highquality iron ore and concentrate as a raw material is very critical to get the best quality iron and steel [1].

Blast furnace The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.

The beneficiation of iron ore typically occurs in a liquid medium. In addition, many pollution abatement devices use water to control dust emissions. At a given facility, these techniques may require between 600 and 7,000 gallons of water per ton of iron concentrate produced, depending on the specific beneficiation methods used.
