1 Froth Flotation – Fundamental Principles
Froth flotation is a highly versatile method for physically separating particles based on differences in the ability of air bubbles to selectively adhere to specific mineral surfaces in a mineral/water slurry.
Phosphate Beneficiation Process
This classification system splits out a +20 mesh pebble phosphate, a —20 +35 mesh fraction for agglomerate separation, and —35 mesh which is the feed to flotation. All classifier overflow and excess water accumulated in the washing steps are diverted back to the large primary hydroclassifier for retreatment. Wet cyclones can be successfully applied in the classification systems to ...
