Flotation: Flotation, in mineral processing, method used to separate and concentrate ores by altering their surfaces to a hydrophobic or hydrophilic condition—that is, the surfaces are either repelled or attracted by water. The flotation process was developed on a …

Froth flotation - kruss-scientific.com

Flotation is a highly dynamic process. Measurement of the dynamic surface tension using one of our bubble pressure tensiometers is therefore also very informative. It provides information on the speed at which the surfactant molecules move through the liquid and how fast they can adsorb at an interface.

Froth flotation - Wikipedia

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. It was the result of the intelligent recognition of a remarkable phenomenon which occurred while they were experimenting with the Cattermole process.
