New Eriez StackCell improves flotation cost and performance
This class of flotation devices is sometimes referred to as "two-stage flotation cells." Eriez developed and patented its two-stage device, called the StackCell in 2008. Today, the company has more than 30 fullscale installations in coal flotation. A cut-away of the Stack- Cell is shown as Figure 2. The design features a tank within a tank.

Improving flotation energy efficiency by optimizing cell hydrodynamics
Comminution of ore is the most energy intensive stage of mineral production and therefore improvements in comminution efficiency can result in significant energy savings (Duffy et al., 2015, Ballantyne and Powell, 2014).In contrast, for froth flotation, which is not energy intensive, optimization has traditionally focused on recovery and final product grade.
