The slurry flow then enters the feed end of the flotation cells. The slurry at this point is called the HEADS of the circuit. The mineral is then separated and flows over the overflow into a trough called a flotation cell LAUNDERER. The OVERFLOW is now called the flotation CONCENTRATE of the circuit.

An efficient flotation separation process is mostly governed by variables from two fundamental aspects: surface chemistry, and hydrodynamics. Judging from the numerous research work reported in the open literature, it can be seen that significant progress has been made of flotation chemistry; however, flotation hydrodynamics …

Dissolved air flotation (DAF) is the water treatment process that clears wastewater by removing unwanted particles such as oil or other suspended solids. In the DAF system, water waste is treated by mixing air with wastewater under some pressure and then releasing that pressure in the flotation tank. This is one of the best and most …
