Air Flow Flotation Machines

Flotation Machine - an overview | ScienceDirect Topics

The most rapidly growing class of flotation machine is the column machine, which is, as its name implies, a vessel having a large height-to-diameter ratio (from 5 to 20) in contrast to mechanical cells. The mechanism behind this machine to is provide a countercurrent flow of air bubbles and slurry with a long contact time and plenty of wash water.

Thus, air flow is already being used to control concentrate grade at Mt. Isa. With the trend to larger and fewer cells, and coarser grinds, it may be advisable to control impeller speeds also, particularly for very coarse feeds, and to find the balance between these two controls for each operation.

This representation indicates that the flotation bay layout employing the larger flotation cells, in this case 2.83 cubic meter (100 cubic feet) machines, occupies less area and reduces installed capital cost by about 25 percent. However, there are instances when the first illustration (selection of small flotation cells) would be chosen for reasons of compactness and symmetry.

On the turbulence-controlled microprocesses in …

01.04.1999· In flotation machines, which still prevails in flotation practice, the operation takes place in a highly turbulent flow (Re D 2 ≈10 6 –7×10 7 in industrial-scale machines). Therefore, the modelling of a flotation process (macroprocess) and its microprocesses necessitate the application of essential results of the statistical turbulence theory. Typical for processing is an extensive ...
