Froth Flotation Process - 911metallurgist

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.
