Metal Profile: Iron Properties and Characteristics

Jan 12, 2020· History . Iron was likely originally discovered and extracted as a result of wood burning on top of iron-containing ores.   The carbon within the wood would have reacted with the oxygen in the ore, leaving behind a soft, malleable iron metal. Iron smelting and the use of iron to make tools and weapons began in Mesopotamia (present-day Iraq) between 2700 and 3000 BCE.

GCSE CHEMISTRY Extraction of Iron in the Blast Furnace

Extraction of Metals. Extraction of Iron.. Chemistry of the blast furnace ().. Limestone is calcium carbonate (CaCO 3) and it is added to the blast furnace to remove the impurities in the iron ore. Calcium carbonate is decomposed by heat in the furnace to give calcium oxide and carbon dioxide. This is called thermal decomposition (see examples of other carbonates).

IRON AND STEEL chemguide

Iron ore isn't pure iron oxide it also contains an assortment of rocky material. This wouldn't melt at the temperature of the furnace, and would eventually clog it up. The oxygen reacts with the remaining impurities to form various oxides. The carbon forms carbon monoxide. Since this is a gas it removes itself from the iron!

Iron Ore an overview ScienceDirect Topics

In a blast furnace, iron ore, fuel (often coke) and flux (often limestone) are continuously supplied from the top of the furnace, while blasts of hot air are blown into the lower part of the furnace. At temperatures of approximately 1500°C, silicate and aluminate impurities from the ore and fuel combine with the flux to form a molten slag.
