Smelt is both a tiny fish and what you do to ore, because English refused to pick a lane.

means To smelt is to heat ore until it melts and separates, freeing the metal trapped inside the rock — and separately, a smelt is a small silvery fish.

from The metallurgical 'smelt' comes from a Germanic root shared with 'melt' — it entered English via Middle Low German or Dutch smelten, tied to furnace work on the continent. The fish 'smelt' is a much older, unrelated Old English word (smelt/smylt) for the same slender, cucumber-scented fish still caught today. Same spelling, two separate family trees — a coincidence of sound, not a shared origin.
