Much of the remaining iron ore resources in Brazil consist of low-grade itabirite ores. Accordingly, a typical beneficiation circuit includes a four-staged crushing/screening plant, followed by grinding in a closed-circuit ball mill, desliming in hydrocyclones and final ore mineral concentration via multistage reverse flotation and thickening of the final product.

The only processing steps used for ores mined from rich deposits (rich ores) are crushing and screening. These ore will be crushed and screened up to particles of about 8 -30 mm. Such ores come mainly from the weathering zones of itabirite deposits. At some mines, washing is combined with the screening of fines ( 6 – 8mm) for sintering process.

Iron ore beneficiation encompasses a wide range of process steps. Crushing, screening and grinding are physical processes used to liberate small particles of differing composition, and are often used together in multiple stages [4], [5]. Thermal breaking has also been suggested as a pre-treatment to reduce grinding costs [6].
