Savona Equipment is a flotation cell supplier worldwide. Froth flotation is a process for selectively separating hydrophobic materials from hydrophobic. This is used in several processing industries. Historically this was first used in the mining industry. Froth flotation improved the recovery of valuable minerals, such as copper- and lead-bearing minerals.

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.
