Froth Flotation - an overview ScienceDirect Topics
Froth flotation will remain a key unit process for the treatment of iron ores for the decades to come with the overarching challenge best described as being the need to modify and improve existing procedures and processing conditions so as to maintain an acceptable iron grade-recovery response in the face of ores and feedstock that will be finer, more complex, lower in grade, more goethitic in nature, and

The effect of particle size distribution on froth ...
2017-8-31 Froth flotation is a complex and widely used separation technique, which relies on differences in the surface properties of the desired particles to the unwanted particles. One of the key parameters in flotation is the particle size distribution of the feed and it has been shown in several studies that the optimal size range for flotation is relatively narrow, approximately 20–150 μm [9] , [14] .
