AbstractGas holdup has been widely considered as potential parameter for the performance prediction of flotation column. However, knowledge about gas holdup in presence of solids is still scarce. This paper presents the relationship of gas holdup with various input parameters in the collection zone of a laboratory flotation column. A 24 factorial design was successfully applied to predict the .
FROTH FLOTATION So many variables influence flotation that it will be long before every one of them can be investigated and its influence on the process determined. The froth flotation process was patented by E. L.Sulman, H. F. K. Pickard, and John Ballot in 1906, 19 years after the first cyanide process patents of MacArthur and the Forests.
