After completion of characterization studies, an attempt has been made to beneficiate the low-grade iron ore fines by selective flocculation using amylopectin as a flocculant and using sodium silicate as a dispersant. Flocculation experiments have been performed by varying dosage of amylopectin and sodium silicate at a pH of 10.

Iron is produced in the United States chiefly from oxide ores. For many years rich hematite ores were produced by open-pit mining in the Mesabi Range near Lake Superior. However, these ores have been largely depleted, and iron is now produced from low-grade ores that are treated to improve their quality; this process is called beneficiation.
