The StackCell, which is much smaller than a traditional flotation cell, can shrink the size of a flotation plant by 50%. The knock-on effect is that it also requires less concrete (smaller carbon footprint), less piping to connect the units, and fewer electrical connections and cable trays and pipe racks, thus reducing CAPEX and engineering ...

For example, eight Jameson cells replaced thirty-two mechanical flotation cells in the Goonyella mine in Australia in 1995, significantly reducing the flotation circuit's size and improving the plant's yield by 3.5% (Carretta et al., 1997). They can also be used to recover fine coal particles from tailings successfully.
Directly and obviously it provides the means for carrying out flotation: (1) Disseminated bubble air through particle attachment is the vehicle by which floatable particles are carried into the froth; this depends upon the volume concentration of bubbles which in turn depends on bubble size and volumetric air flow rate; (2) Additionally, air ...

The slurry flows through this line of cells until all the mineral that is economically feasible to recover has been retrieved. Let's look at this for the whole flotation bank now. One of the things to remember, with these cells, is that whatever change is made to each individual cell will affect the remaining cells in that bank of cells.

Gravity separation relies on the difference in density between chromite and other minerals, while magnetic separation uses magnetic properties to separate the ore. Flotation involves the use of chemicals to selectively separate chromite particles from the rest of the ore. ( Chrome Plant Process Flow Explained - Flotation machines )
