Eriez® Flotation has completed fabrication and water testing of the first StackCell® SC-200 high-rate flotation
machine at Eriez World Headquarters in Erie, Pennsylvania, USA. The SC-200 is the newest addition to the StackCell product
line and is the highest capacity unit ever built at nearly 300 m3 of equivalent conventional flotation capacity within a 65 m3
flotation cell. This is the first of two StackCell SC-200 cells that will be delivered to a copper concentrator in Q4 2021 to provide
additional rougher circuit capacity.
Speaking of this achievement, Eriez’ Vice President of Global Flotation
Business Eric Wasmund noted, “The StackCell is a breakthrough technology
that provides a unique solution to many environmental and sustainability
challenges for the mining and metals sector. Our company has worked
diligently to develop and commercialize the StackCell technology, and this
milestone brings us one step closer to achieving this goal.”
The StackCell is a two-stage flotation machine that reduces flotation
volumetric requirement and improves recovery of fine particles and slow
floating minerals. The key feature of the StackCell is a high shear contacting
chamber that is isolated from a quiescent separation chamber, which allows
for independent optimization of the particle collection process and the froth
recovery process. The StackCell achieves a 75 to 80% reduction in
residence time requirement by increasing the flotation rate constant of
minerals through introduction of air and particles directly into a high-shear
contacting chamber with a multi-stage rotor-stator mechanism. This device
has an extremely high specific energy input that is translated to turbulent
kinetic energy through the rotor blade design and generates four to five
times higher turbulent dissipation rates compared to conventional flotation
machines.
