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.
Design and selection of correct flotation equipment is critical to the success of any flotation concentrator. Traditionally, selection has been based on residence time scale-up from batch …
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.

In the mid-1960s, flotation cells were commonly 5.7 m 3 (200 ft 3) in volume or less (Figure 12.65). In the 1970s and 1980s flotation machines grew in size and typically ranged from 8.5 to 28.3 m 3 with larger cells being increasingly adopted. Manufacturers in the forefront of the industry included Denver Equipment, Galigher, Wemco, Outokumpu ...

The model's choice of a laboratory flotation machine depends on three things; What work you want to do with the machine; Who you have to operate the machine; How much you have to spend; If its just for some 'hot' plant floats and some basic metallurgical testing onsite then my personal favorite is the old Denver D12 machines.
