  • Synoptic view on P ore beneficiation techniques

    2022.4.1  The most widely used beneficiation techniques are flotation, direct carbonation, electrostatic up-gradation, calcination, and leaching/bioleaching. Bioleaching has environmental benefits and electrostatic up-gradation can achieve the highest quartz removal efficiency, although this is an energy-intensive process.
