Abstract

Procedure for recovering a floating body in a thin layer state on the surface of a liquid mass, characterized in that the liquid is subjected, near its surface, to a local rotational movement about at least one substantially vertical axis, in order to cause the formation, on the liquid surface, of at least one depressed area open and widened upwards, thus said depressed area constituting a cavity in which the body from the layer runs and accumulates with a thickness superior to that of the layer, and because the body that accumulates in it is extracted from said cavity, said extracted quantity being automatically replaced, as it is extracted, by the body coming from the layer.
