The use of power ultrasound in mining. L. Gaete-Garretón, in Power Ultrasonics, 2015 35.5.1 The flotation process. One of the most used processes to concentrate mineral from a mine is flotation. To perform a flotation process the mineral is finely ground (particle sizes between 50 and 150 μm), then the ground mineral is mixed with water in a container called a flotation cell.

Over the past few decades, the need to process more minerals while lowering capital costs has led to an increase in the size of flotation cells, e.g., 0.03 m3 to 1000 m3. However, this increase has created new challenges in the operation and design of industrial flotation cells, particularly in terms of froth removal, because the distance the froth must travel …
