Limestone – Its Processing and Application in Iron and,
07/07/2017· Limestone is also one of the vital raw materials used in production of iron and steel. Limestone, by definition, is a rock that contains at least 50 % of CaCO3 in the form of calcite by weight. There can be small particles of quartz (silica), feldspar (alumino-silicates), clay minerals, pyrite (iron sulphide), siderite (iron carbonate), and other minerals associated with the limestone.
Why is limestone used in extraction of iron,
05/02/2021· Why is limestone used in extraction of iron? (1) The ore of iron contains acidic gangue or impurity of silica, SiO2. (2) To remove silica gangue, basic flux like calcium oxide CaO, is required, which is obtained from the decomposition of limestone, CaCO3. Therefore in the extraction of iron, lime is used.
What is the use of limestone of in the extraction of iron,
Limestone is used as a flux in the blast furnace. The limestone is added to the iron ore burden of the blast furnace in the amount of ~117kg per tonne of “hot metal” (steelmaker’s slang for the liquid iron produced by the blast furnace). This produces the slag of 181kg per tonne of hot metal which contains most of the impurities: 38% SiO2, 36% CaO, 14% MgO, 9% Al2O3, plus minor

How is Iron Refined from Ore? (with pictures)
The heat generated inside towering blast furnaces is used to create pig iron from a mixture of iron ore, coke, and limestone. To create an even purer form of iron, known as pig iron, limestone must be added to the mix and the heat increased. This is done contemporarily in the silo-like structure known as a blast furnace.
