Iron smelting - SCA

Ore-dressing The process began by breaking the ore into pieces about the size of a man's fist, which was back-breaking work. Then it was dressed in the furnace to burn off water and other impurities like sulphur and carbonic acid. Dressing involved heating the iron ore to dry it, but not smelting it. After the ore-dressing came the crushing ...
