Flotation separation of plastics can be enhanced by differences in hydrophobicity In addition flotation separation improves if the most hydrophobic plastic that floats has a lamellar shape and lower density and if the most hydrophilic plastic that sinks has a regular shape and higher density The results obtained show that froth flotation
Floatation Separation Floatation is a main method to separate the ores by the different natures of wetting by water The hydrophobic mineral will be gathered on the bubbles and floats on the surface However the hydrophilic minerals will stay in the water Applies for the following ores
