Kind Code:
B2
Abstract:
The present invention relates to a method and an apparatus for gathering valuable substances, such as uranium, gold, silver or the like from sea water. The features characterizing the invention are that the sea waves are caused, by using the energy thereof, to rush up a ramp (2) which leads the waves into a basin from above, which thereby is filled to a level (By) higher than the external stillwater surface (Ly), the water quantity within the level difference ( DELTA H) applying a hydrostatic pressure which brings the water in the basin to flow through one or several layers of filters (4) containing sorbing, ion-exchanging or bioactive mass, whereafter the water is directed back to the sea on a level lower than the upper edge of the ramp (2).
