Effect of Ultrasonication on the Flotation of Talc

Jun 17, 2004 The natural hydrophobicity of talc was depressed by the use of ultrasonic treatment during flotation. The recovery of the talc decreased by nearly 30% after 4 min of ultrasonic preconditioning. In addition, two talc depressants, namely, IMP4 and carboxymethyl cellulose (CMC), were compared during ultrasound treatment. The guar gum IMP4 showed a better depressant ability
