Froth Flotation Techniques

Froth flotation is one of these techniques which is based on hydrophobicity differences between particles Unlike minerals most of the plastics are naturally hydrophobic thus requiring the addition of chemicals that promote the selective wettability of one of its components for a flotation separation

Aug 26 2012 Principles of flotation Flotation is a physico chemical separation process that utilises the difference in surface properties of the valuable minerals and the unwanted gangue minerals The theory of froth flotation is complex involving three phases (solids water and froth) with many subprocesses and interactions and is not completely understood.The performance of the froth phase usually evaluated as froth recovery determines overall flotation performance In most flotation operations recovery across the froth is rate controlling consequently understanding the froth phase is very critical Although much research effort to understand the physics of the froth has been expended not many techniques to optimise froth recovery have been.
