Flotation Behavior Of Malachite Using Hydrophobic Talc

recently, nanoparticle flotation was suggested as an alternative to the conventional process. In nanoparticle flotation, nanoparticles are use as collectors and their deposition onto the target particles is governed by physicochemical interactions 7,8.hence, unlike the typical Cu oxide mineral flotation process mentioned above, a sulphidization step is not required.

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 min of ultrasonic preconditioning. In addition, two talc depressants, namely, IM and carboxymethyl cellulose were compared during ultrasound treatment. the guar gum IM showed a better depressant ability
