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. The particles with attached air bubbles are then carried to the surface and removed, while the particles that remain completely wetted stay in the liquid phase. …

The P 2 O 5 content of coarse particles boosted from 12.51 to 26.80 % after treatment (milling, attrition, and froth flotation); in the last stage, froth flotation allows an increase from 25.44 % after attrition to 26.80 %. These results are encouraging and the process can be applied to industrial scale.
