Blast furnace - Wikipedia

A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...

what is a flow diagram in chemistry of how iron is extracted

Iron is extracted from its ore in the blast furnace.. The main iron ore is called haematite. Haematite is iron(III) oxide - Fe 2 O 3. The iron ore contains impurities, mainly silica (silicon dioxide). Limestone (calcium carbonate) is added to the iron ore which reacts with the silica to form molten calcium silicate in the blast furnace. Read More
