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.
Jameson Cell has accurate scale-up reliability and is the real-word specification in any and all duties within a flotation circuit: rougher and scavenger duty; cleaner and cleaner scavenger duty. In fact, a single Jameson Cell has successfully replaced a traditional circuit of cells; and unlike other competing cells, it has no moving parts.

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 …
Cytec Handbook. Capacity. Floating time of the ore is one of the determining factors in figuring the capacity. If an ore is slow floating and requires twelve minutes treatment time, and another ore is fast floating and requires but six minutes treatment, it is evident that a machine of only half the capacity is necessary in the last instance.

Almost all successful models of the flotation process have been based on the premise that flotation is a kinetic process. In this way a model can be formulated in terms of a rate of flotation which can be quantified in terms of some of the many chemical and physical factors that define the environment inside a flotation cell.
Flotation is a science that brings together many complicated variables. Factors include knowledge of mineral structure, chemicals, temperature, technical skills of the operator and dependability of the flotation cell.

where. r p:. Radius of mineral particles; r b:. Radius of bubbles. As seen from Formula (), collision is affected by the mineral size and the bubble size and is proportional to the mineral size.The larger the mineral size is, the greater the inertia force is and the greater the contact probability is; collision is in inverse proportion to the square of the bubble size.
