The final stage in iron ore processing is ironmaking, where the iron ore is transformed into molten iron through a process called reduction. The most common method of ironmaking is the blast furnace route. In a blast furnace, iron ore, coke (carbon), and fluxes (limestone or dolomite) are loaded into the furnace from the top.

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.

Iron ore beneficiation is the process of improving the quality of iron ore by removing impurities and increasing its iron content. It is necessary to reduce alumina and silica in the feed. The process improves the chemical, physical, and metallurgical characteristics of the ore to make it a more desirable feed for iron-making furnaces.
