Effect of ultrasonication on the flotation of talc
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 ...
Recovery of chromite fines from wastewater streams by column flotation
In the Western Chrome Mine in South Africa, the process water stream contains approximately 3% chromite fines (<100 μm), which report to the tailings dam. This results in resource loss and water contamination. Consequently, ...
Batch flotation of a complex sulphide ore by use of pulsated sparged air
Pulsation of air sparged into the flotation cell of a complex sulphide ore led to vibration of the bubbles in the pulp, and enhanced bubble-particle collision. The thinning and destruction of the intervening thin liquid ...
