Very cool thought experiment! I used to daydream about this as a lad.

I think a huge part of our early progress came from a basic "let's
increase it!!" attitude, where "it" is, say, the size of a fire, or the
force with which a rock is struck, or the distance one ventures out away
"Cool! Fire! Let's make it bigger, REALLY big!" -- I think that might be
how metals were discovered (qua substances that could be melted, would
harden, and retain their new shape). (It might also have been the result
of an inspection of the results of an accidental fire.) Some rocks, or
parts of rocks, near the huge, hot fire melted more easily than others.
(And eventually someone built a fire in a large indent in a cliff wall,
the wind blew hard, the fire roared, and someone said "Let's figure out
how to blow on the fire -- even harder than the wind!") People who had
ventured far from home might then say "Hey, I saw rocks in a cave in the
valley across the way that look like that one that melted quickly," etc.
On the new planet, if I were in charge of metal, I'd look around for
rocks that seemed to have metallic strips in them (all this is
pre-Google guessing), and put them in a some kind of fireplace with a
bellows, and some way to catch the melting metal. But mostly I'd be
trying to slow the aging process so that we would live long enough to
reach the level of, say, the ancient Greeks (easily doable, I think).
