Utilization of Iron ore fines using flocculating reagents

Abstract

Abstract The wastewater treatment is being given more importance nowadays, especially those which are not from the biological processes. If the polymers used for flocculation purpose are so that they do not cause harm to the water bodies and are environment friendly then they are being given more importance. We propose here a very simple flocculent which is prepared by blending of Polyvinyl alcohol (PVA) and Polyacrylic acid (PAA) which is safe for the water bodies and effective too. The proposed polymer has been successfully tried upon the iron ores flocculation tests at 0, 15, 20 and 50ppm. The obtained results were analysed for its iron content; they indicated enhancement of iron ore grade from 52.6% to 70.37% at 50ppm flocculent dose. The percentage recovery was found to be more for 15% pulp density at 20 % flocculent dosage.
