Minerals Free Fulltext Talc Flotationan Overview

Talc is a naturally hydrophobic gangue mineral in most sulfide ores. However, talc has vast applications in the cosmetics, paper, and paint industries due to its high chemical stability, and its demand continues to grow. Since flotation is the most effective beneficiation technique for upgrading sulfides, the high hydrophobicity of talc has made its selective separation challenging.

Effect of Ultrasonication on the Flotation of Talc

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
