flocculation of low grade iron ore

  • Comparison of selective flocculation of low grade

    This study aims to beneficiate low grade goethitic iron ore fines using a selective flocculation process Selective flocculation studies were conducted using different polymers such as starch amylopectin (AP), poly acrylic acid (PAA), and a graft copolymer (APgPAA) The obtained results were analyzed; they indicate the enhancement of the iron ore grade from 5849% to 6752% using APgThe response of lowgrade iron ore flocculation was investigated using a twolevel and threevariable factorial design From the studies, the optimal conditions were found to be pH (10), pulp(PDF) Enhanced recovery of low grade iron ore by selectiveMechanism of polymeric adsorption in selective flocculation of lowgrade iron ore Diptimayee Nanda Department of Fuel and Mineral Engineering, IIT (ISM) Dhanbad, Dhanbad, Jharkhand, India Correspondence pujananda93[email protected] of polymeric adsorption in selective
