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].

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.
