Utilization of Iron ore fines using flocculating reagents

Journal of Physics: Conference Series, 2021
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
