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 a flotation column is usually . water washed, with approximately as much wash water as there is water reporting to the froth. The water is most commonly added via pans, perforated with 4-8 mm diameter holes, located 20-30 cm above the froth, thus generating a rain of water onto the surface of the froth.

The shape and size of the bubbles in the froth directly affect the amount and purity of the concentrate overflowed during the froth flotation of the coal. The froth structure is significantly dependent on parameters such as the size of the ...In the not too distant past, flotation loses were commonly 50 , reaching as high as 90 for coarse particles. Looking to resolve these substantial losses, FLSmidths goal was to create a product that allowed customers to have more control over the froth recovery process. With this goal in mind, the Froth Recovery Upgrade Package was designed.
