FOR COLUMN FLOTATION APPLICATIONS Viviana Ramirez Coterio ABSTRACT Column flotation cells have become the most popular machine design for industrial appliions that require high purity concentrates. The superior metallurgical performance of column cells can be largely attributed to their unique geometry which readily accommodates the use of froth washing systems. This unique feature .

Many plants replaced mechanical cells by columns in the cleaning stage and obtained higher recovery of fine particles [30] . The bubble sizes are usually smaller in flotation columns and it is a function of the gas rate [28] [31] and the type of sparger used [25] . Desliming

 · It may be due to the turbulence generated by higher superficial gas velocity. Quality of mixedness increases in the flotation column due to liquid recirculation as turbulence caused by tiny bubble motion. The liquid circulation caused by superficial gas velocity is responsible for the rate of mixing and recovery efficiency of flotation column.

Flotation columns that were developed by the mineral industry for the separation and recovery of ores [14, 15] use these same flotation principles as horizontal cells. Compared to them, flotation columns have a greater heightto width ratio and are equipped with a downwards washing shower to prevent entrainment of the longer fibres. Advantages of the column over conventional flotation cells ...

 · The maximum recovery predicted by the fitted Kelsall model was 100% at all CTAB concentrations, but only at the higher air flow rate (2 L min1), indiing that the recovery of microalgae cells is favored at high air flow rates. The flotation of the fastfloating particles was faster than that of slowfloating particles. The air flow rate had larger effect than the slight increase in the ...

flotation rate, particle size recovery, air flow, pulp density, etc.) As a result, it is difficult to study the effects of any single factor in isolation, and compensation effects within the system can keep process changes from producing the expected effects (Klimpel, 1995). This makes it difficult to develop predictive models for froth flotation, although work is being done to develop simple ...

to column flotation, resulted in a higher grade and recovery of PGM as compared to conditioning by means of the recirculation pump. The PGM grade when gentle conditioning was employed was 9 ppm higher for a common PGM recovery of 80% for both conditioning techniques. Finally it was found that increasing the column height improved the graderecovery relationship. The PGM grade obtained by .
