Iron was a metal of mythical character. For thousands of years before they learned to smelt iron ore, Egyptians were crafting beads and trinkets from it, harvesting the metal from fallen meteorites (3500-500 BC). This ancient Egyptian iron bead dates back to roughly 3300 BC. Photo The Open University / The University of Manchester

What is the use of limestone of in the extraction of iron

Answer Usually, limestone (calcium carbonate, CaCO3) is calcined in a lime kiln, where it is heated to form lime (CaO) and CO2 gas. The lime is then used in both steelmaking furnaces to refine liquid iron into steel, and also on ladles as slag to further refine the steel. It absorbs impuritie...

The Making of Iron Steel

The Making of Iron Steel

Iron ore, as mined, is a combination of iron with oxygen and various other unwanted substances, generally known as gangue. The first metallurgical step is to reduce iron ore to metallic iron, a process which is mostly carried out in a blast furnace, using coke as both a fuel and reducing agent.

Ironmaking 101 From Ore to Iron with Blast Furnaces

Oct 10, 2017 Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface ...
