Froth flotation

Froth flotation is a process for selectively separating hydrophobic materials from hydrophilic. This is used in mineral processing, paper recycling and waste water treatment industries. Historically this was first used in the mining industry, where it was one of the great enabling technologies of the 20th century.

Flotation in boat hulls

Everyone must admit that having positive flotation value aboard a boat is a good quality, and in theory, enough flotation material or devices can conceivably make a boat that is IMPOSSIBLE to sink. Yet for every cubic foot of flotation value added, we must also give up that amount of space in our boat that could be used for something else. If
