Iron Ore Smelting Process - Bright Hub Engineering
The ore is loaded into a blast furnace along with measured quantities of coke and limestone. Hot coustion air is supplied to the furnace and some form of fuel used to raise the temperature. The iron is reduced from the ore by carbon in the coke, the limestone aiding slag separation from the molten iron. The slag and molten iron are tapped off from the bottom of the furnace, the slag being

gas from iron ore used to light
Cast iron has been found in China dating to the 5th century BC, but the earliest extant blast furnaces in China date to the 1st century AD and in the West from the High Middle Ages. They spread from the region around Namur in Wallonia in the late 15th century, being introduced to England in 1491.The fuel used in these was invariably charcoal.

Blast Furnace operation: HOW A BLAST FURNACE WORKS
Iron oxides can come to the blast furnace plant in the form of raw ore, pellets or sinter. The raw ore is removed from the earth and sized into pieces that range from 0.5 to 1.5 inches. This ore is either Hematite (Fe 2 O 3) or Magnetite (Fe 3 O 4) and the iron content ranges from 50% to 70%.) and the iron content ranges from 50% to 70%.

Iron | Geoscience Australia
Iron is about eight times heavier than water (its relative density is 7.87). When iron is exposed to air it starts to turn back into iron oxide and the red powder that forms on the surface of iron is what we call rust. You may have seen rust on old cars or old iron sheds.
