Abstract

The invention concerns a method for recuperating polluting liquids, in particular hydrocarbons spilled at sea, which consists in raising the polluting spill (10) by froth flotation, using air bubbles, up to the level of the tank (6) receiving the foam formed by the air bubbles covered with a polluting liquid film.
