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.

addition and recovery or grade. A closer look at the froth-depth data during this period indicated that the froth levels in the flotation cells were oscillating. Hence it was concluded that it was not feasible to measure and model the effect of xanthate on grade or recovery while there are oscillations in level.
