    2020-9-18 · As for the ratio of iron-ore to finished iron as far as we can tell ancient iron-working was a lot less efficient than modern iron-working. From raw ore to finished goods the estimates range from 8-16 of the mass of the ore ends up in the finished product. Not quite enough to explain the discrepancy but still a big gap from modern figures.

Metallic iron is carbonized by carbon in the coke and CO gas and melts at 1200–1300 °C. Molten iron and slag drip down through the coke layer to the hearth where they reach their final temperature and composition.
