Irondale was originally known as Pottsdale, for Samuel Potts, who started a salt operation at Yellow Creek circa 1806. In 1869 Morgan & Hunter laid out the original plat of what was then called Hunterville which later was changed to Irondale after the discovery of iron ore and other minerals used in the manufacture of tin. Coal mining began at the settlement in 1861. A blast furnace was built later to supply iron to the tin mill which gave the town its new name, Irondale. The first commercially successful tin mill in the United States operated in Irondale in the 1880s.
