(B) Someday, it may be worthwhile to try and recover uranium from seawater

(D) To try for the recovery of uranium out of seawater may someday be worthwhile

When we say, try to recover, there is only one action (try) and the infinitive to recover modifies the action of trying. What kind of trying? The trying related to recovering stuff.
