flotation froth colour and structure are commonly recognised as important visual features in the control of the industrial flotation performance. in this perspective, the visual appearance of a froth surface can be analysed using digital imaging procedures able to describe the morphological e.g. sadr-kazemi and cilliers, 1997 and colour
concentrations. the traditional flotation cell consists of a stirred tank incorporating air injection. in recent decades columns have appeared to offer advantages for platinum flotation. this project is a comparative study of the use of column and mechanical cells as cleaners for the flotation of an ug-2 upper group 2 platinum ore.
as an example when trying to float native copper, no evidence could be found that a particular flotation machine would be more suited to enhance native copper recovery in a flotation cell. several process or mineralogical aspects, e.g. particle size, liberation, floatability, reagent regime etc. will play a larger role in the recovery of the native copper minerals than the particular type of cell used.
the task for the sub-a flotation machine-cell design is solid as it is made of heavy steel joints are electric welded both inside and out. partition plates are furnished with gaskets and arranged for bolting to partition channels so that if necessary all of the plates can be changed at any time in the field to provide either a right or left hand machine.

key words : column flotation, theory and practice, applications. introduction separation of valuable minerals from gangue is far from ideal in conventional mechanical cells. column flotation, invented in the early sixties, proved to be a better alternative to the conventional cells. the main advantages of column flotation are : i improved recovery,
the flotation of large particle coal has also been tested with the shallow air flotation machine. coal as large as minus ½ plus 3/8 inch with a specific gravity of 1.39 was floated with the shallow air cell; this is as large as is considered theoretically possible to float.
froth flotation cells to concentrate copper and nickel sulfide minerals, falconbridge, ontario. froth flotation is a process for separating minerals from gangue by taking advantage of differences in their hydrophobicity .

for ultra-fine particles, the theory suggests that the rate of flotation can be improved by increasing the rate of shear in the suspension of particles and bubbles. a new cell has been developed, the concorde cell, in which the pre-aerated feed is raised to supersonic velocities before passing into a high-shear zone in the flotation cell.
the seven theories of flotation therapy. via michael hutchison, author of the book of floating: exploring the private sea. there's no doubt that floating works - as a therapeutic, educational and entertainment tool it has powerful effects on a number of levels, including the physical, emotional, intellectual and spiritual.
flotation cell machine for gold recovery plant in 2008, an iron ore flotation plant in sudan purchased this type flotation machine. each index of bf flotation cell is better than 5a flotation cell, single capacity saves 23.96% power, in the case of the selected iron coarse and concentrate grade is lower than 20%, iron recovery rate
