“Recover x out of y” is incorrect. The correct idiom is “recover x from y”.
With this option, “this process” of the non-underlined part will refer to “trying to recover uranium”. Logically, “this process” should refer to “recover uranium”.

“To try to recover uranium” is much better than “to try for the recovery of uranium”, just as “to try to reduce weight” is much better than “to try for the reduction in the weight”. The first construction emphasizes the action that is being tried.
