Flotation Flotation is a process designed for specific solidsolid mixtures It works by generating gas bubbles in a liquid that attach to selected solid particle Afterwards the particles rise to the liquid surface where they are removed by an overflow weir or mechanical scraper

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic This is used in mineral processing paper recycling and wastewater treatment industries Historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th century

In fortytwo chapters it explores all major egories of separation including those involving phase changes extraction chromatography ionexchange resins electric fields flotation membranes and miscellaneous techniques

May 05 2010 nbsp 0183 32Froth Floatation Process Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic This is used in several processing industries

Flotation Frothers What is the Function of Frothers The function of frothers in flotation is that of building the froth which serves as the buoyant medium in the separation of the floatable from the nonfloatable minerals Frothers accomplish this by lowering the surface tension of the liquid which in turn permits air rising through the pulp to accumulate at the surface in bubble form

Some methods of separation are distillation crystallization centrifugation cromatography ion exchange solvent extraction flotation sieving
