Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the …

The pulp density has a significant impact on the degree of aeration and residence time of the pulp in the flotation cell, the volume concentration of the flotation reagent, and the bubble-to ...
The roles of three major components of the Reflux Flotation Cell are introduced. • The flux mechanism formed in the boundary of major components is discussed. • Three theories adapted to characterise the Reflux Flotation Cell were explained. • The operating parameters of the Reflux Flotation Cell were evaluated. •
Variables of hydrodynamics are equally important as those of surface chemistry in determining the efficiency of froth flotation processes. In a mechanical flotation cell, macro hydrodynamics is responsible for solids suspension and aggregates transport, and micro-turbulence plays an important role in the sub-processes of …
flotation circuit. Flotation cells have three main control parameters (1) reagent dosing rate (2) froth depth and (3) air addition rate. Many other parameters may vary such as feed rate, particle size distribution and head grade, however these are the output of upstream processes and are not controlled in the flotation circuit itself.
