| 説明 | Smelting is used to extract iron from iron ore, Smelting uses heat and a chemical reducing agent like charcoal. The carbon (from the charcoal) or carbon monoxide derived from it removes oxygen from the ore to leave the metal. The heat causes the sand to melt and flow away from the Iron. The temperature has to be kept low enough so that the iron does not melt |
