At present, large mechanical flotation cells of 100 to 300 m 3 are used in rougher operation in different industrial flotation plants around the world. However, in spite of the advances in fundamental research and the notable growth in equipment size, there is still a lack of reliable data for industrial flotation modelling and simulation.
The design of each circuit is customized in terms of cell sizes, configurations and layout based on the available flotation testwork data. Utilizing either conventional flotation machines, tank cells, flotation columns or a combination of the three, Westpro can deliver high quality modular flotation solutions for any project scale.

Vera et al. (1999) investigated the relationship between the overall flotation rate constant and froth depth treating a copper ore on a mechanical flotation cell for a series of different cell operating conditions. It was shown that there is a linear relationship of negative slope between overall flotation rate constant and froth depth, i.e ...

The flotation cells were run at different froth depths for this test, as recorded in the published dataset. The model was adjusted to represent this froth depth. Due to the water recovery not being included in the flotation model it was input as a fixed parameter in the form of solids percentage of the concentrate streams.
These banks of larger industrial froth flotation cells are modern reconstructions of the classic DENVER Flotation machine designs. Made to order to any size/volume and cell per bank you need.

The effectiveness of flotation relies on the interaction of multiple factors, including particle characteristics, hydrodynamic conditions, and gas dispersion [2]. An example of a froth …
Of these, perhaps the most interesting is the fact that, from the point of view of simulator structure, all the flotation cells in the plant are identical. This configurational simplicity is further enhanced by the fact the model equations for the performance of individual cells do not change from cell to cell. The model equations are naturally ...
