Don't be an ignorant smartass! Surveys from the Apollo sampling expeditions
show lunar soil to be quite rich by earth standards, if I recall correctly a
few percent? With abundant sunlight for energy, abundant free soil to process,
and abundant unused real-estate to dump the unwanted portions (mostly oxygen
silicon and aluminum if I remember correctly), we could set up a titanium
production plant within ten years if we had funding. We can be very sloppy,
recovering only half the titanium in the soil and dumping the rest with the
waste materials, thus simplifying the engineering and chemistry. There's no
need for alchemy, simple inorganic chemistry and electrolysys will do it.

Instead of spending millions to make the system fully automated for
all those little problems that can occurr, why not include some
people to help out?  A small team could help set up the equipment
in a couple of days and return to the space station to monitor it.
Then when something breaks, they can go fix it.  It should be
relatively cheap to make a few updated lunar modules for temporary
visits to the Moon.  All you need is a lunar ferry (you'll need that
anyway to return the titanium).
