@Machine Medic: That's true, but we wanted to keep those processes as simple as possible (since it's just a game)
Actually you can find native aluminium and cobalt in the world, but they are very rare. Tungsten hasn't been found yet (but that does not mean that native tungsten does not exist^^).
Eventually we will change it in the future, depends on how much we will go into detail about those processes
