Abstract
The StackCell flotation technology offers significant metallurgical and design benefits that are a result of a superior rate of flotation when compared to conventional, mechanical cells. This improvement in flotation rate is the combined result of pre-aeration techniques, high-shear contacting, and a quiescent phase separation. In addition, high-grade products similar to that achieved in column flotation applications are also possible due to the addition of wash water that is distributed over a deep froth. Design considerations for this new technology are discussed relative to both lab- and pilot-scale test data.
