Froth flotation is a process for selectively separating hydrophobic materials from hydrophilicThis is used in mineral processing paper recycling and waste water treatment industri Historically this was first used in the mining industry where it was one of the great enabling technologies of the 20th centuryAnd as a comment I have witnessed more voodoo and spurious claims of efficiency in the froth flotation machine design than anything since the snake oil days of the Old West It is generally wise to stick with a good brand that is widely utilized in flotation of the mineral desired

the ore waste tailings The froth flotation process separates the lighter minerals from the heavier waste tailings In froth flotation cells the pulverized ore particles are fed downward via a pipe into a large tank where they are mixed vigorously with water a reagent that promotes bubble attachment and compressed air or inert nitrogen gasNot including the froth zone transport and stability implies that kinetic models are not sufficient for understanding the effects of tank scale on flotation so they cannot be used for effective tank design The design of large flotation tanks is the focus of the next section 32 Machine design scale up

Froth flotation is a physico chemical separation process Separation is principally based on differences in surface hydrophobicity However particle size and density have a significant impact Initial flotation patent and application was developed for graphite by the Bessel brothers Similar to graphite coal is naturally hydrophobicFurther Developments in the Control of Level Abstract in Flotation Columns M H Moys froth phase results in a loss in grade tape is widely used for the measurement of fluid level in tanks its use in colu n flotation must be seriously questioned since

Froth handling Each RCS tank is provided with double internal cross flow launders for effective froth removal and minimal froth transport distance • Both launders discharge to one side of the cell to simplify froth handling RCS Flotation machine • Froth crowder plates can be easily pro vided to reduce froth residence times forCOLUMN FLOTATION MODELLING AND TECHNOLOGY JB YIANATOS reporting to the froth The method of minimizing entrainment is to create a 5 3Ocm thick froth at the slurry surface The froth permits the gangue to drain back to the pulp while mechanical flotation units both in design and operating philosophy This has been a cause

Induced gas flotation IGF is a water treatment process that clarifies wastewaters or other waters by the removal of suspended matter such as oil or solids The removal is achieved by injecting gas bubbles into the water or wastewater in a flotation tank or basinThe conditioned mineral slurry is then processed in flotation cells which are fundamentally distressed tanks into which finely dispersed air bubbles are introduced The desired hydrophobic mineral will then attach to the air bubbles and float to the top of the flotation cell where it will be skimmed off as a mineral laden froth
