If I'm not mistaken, right now the Ore Conversion cost for Uranium Creation from Rich Stone is similar to that of other ores - Rich Stone + pre-existing Uranium Ore. Do you figure it's worth including a Sulphuric Acid component to this, in order to make the recipe roughly equal to standard Uranium mining requirements? So Rich Stone + Uranium Ore + Sulphuric Acid = more Uranium Ore? I'm honestly not sure, myself, but I figured it was worth bringing up as a question.
