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, ...
The interpretation of flotation froth surfaces by using digital image analysis and neural networks
The rapid developments in computer vision, computational resources and artificial intelligence, and the integration of these technologies are creating new possibilities in the design and implementation of commercial machine ...
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 ...
The classification of froth structures in a copper flotation plant by means of a neural net
By making use of grey level dependence matrix methods, digitized images of the froth phases in a copper flotation plant were reduced to feature vectors without losing essential information of the characteristics of the ...
