goethite-rich mineral tends to generate fine fraction known as fine ore having size below 8 –10 mm. Dry processing of iron ore is popular for treating hard massive hematitic ores; however, fines generated during processing of goethite-rich mineral cause significant quantity loss of iron values in rejects and make the process inefficient.

It has been estimated that approximately 65-75% of sponge iron production cost is attributed to the cost of raw materials (Indian Bureau of Mines, 2011). As a measure to improve process flexibility and reduce operational costs, DR processes resort to the use of fine ore instead of lumps, as well as cheap waste gases (Friedl et al., 2018). Table 1.

Until the 1950s of the last century, the oxidized iron ores that were loaded into the blast furnace had granulometries within 10 and 120 mm. However, the depletion of high-grade iron ore sources has made necessary the utilization of concentration processes with the purpose of enriching the iron ore. Because of these processes, a fine granulometry is …
