The extraction process has been demonstrated by the JAERI (Japan).
The other thing is that as rivers carry each year almost 50000 tons of uranium to the oceans, from erosion, this ressource can even be considered as renewable...

The other thing is that there is so much uranium from conventional mines that it may never be necessary to tap seawater uranium, if we develop fission breeder reactors, or if fusion works (and is cost effective...)
I just like to recall that seawater uranium may be as renewable as wind and sun because it is a bit provocative idea.
(try to say this to a nuclear opponent !)
