taking something crude and beating it into something you'd actually pay for.
means the process of removing impurities from a raw material to produce a purer, more useful, more valuable version of it.
from from latin refinare, re- plus finis meaning to bring to an end or finish properly; medieval sugar makers used it for boiling raw cane down to clean crystal, and the word migrated to metals and oil as those industries scaled up.
