FLOTATION is a physico-chemical separation process that utilizes the difference in the surface properties of the valuable and gangue minerals. FROTH FLOTATION involves three different phases- solid (fine ore powder), liquid (water) and froth. The process of separation of mineral includes three important mechanisms 1.

The perfect combination of chemicals and flotation cell design is the key for a high-efficiency flotation process. Further, this ability to make refinements and adjustments to multiple elements of the process is part of what gives froth flotation an advantage over other processes.

Froth Flotation Basics Froth flotation is defined as a surface-chemistry-based process for the separation of solids that takes advantage of the differences in wettability at solid particle surfaces. Solid surfaces are often naturally wettable by water and are termed hydrophilic.

In this situation, it is possible to have too little froth area, making froth removal the rate-controlling step in the flotation process. An extreme example of this occurs where the largest available cells are not suitable due to froth area limitations, yet may satisfy the old lip length rule.

Froth flotation is one of the processes used to recover recycled paper.In the paper industry this step is called deinking or just flotation. The target is to release and remove the hydrophobic contaminants from the recycled paper. The contaminants are mostly ink and stickies. Normally the setup is a two stage system with 3,4 or 5 flotation cells in series .

flotation process, in mineral treatment and mining, process for concentrating the metal-bearing mineral in an ore . Crude ore is ground to a fine powder and mixed with water, frothing reagents, and collecting reagents. When air is blown through the mixture, mineral particles cling to the bubbles, which rise to form a froth on the surface.

While the buoyancy analysis has been greatly simplified for the sake of brevity, it should be apparent that the intentional elimination of a distinct froth phase of discernable depth and the creation of a fluidized bed of solids make it possible for the HydroFloat technology to recover much larger particles than traditional froth flotation machines.

Feb 29, 2008Best Answer Froth flotation is a selective process for separating minerals from gangue by using surfactants and wetting agents. The selective separation of the minerals makes processing complex (that is, mixed) ores economically feasible. The flotation process is used for the separation of a large range of sulfides, carbonates and oxides prior to further refinement.

The froth of copper-rich bubbles at the top of the tank is then skimmed off for further processing. The gangue sinks to the bottom of the tank to be removed or disposed of as mine tailings. The next stage after froth flotation is the thickening stage. The froth is poured into large tanks called thickeners.
