What is the use of limestone in a blast furnace? |

16.09.2008· Limestone is calcite or calcium carbonate, i.e. CaCO(3). By heating calcium carbonate it is thermally decomposed into calcium oxide (quick lime), CaO, and carbon dioxide, CO(2). It is this calcium oxide that is added to the process. The primary impurity in any ore is silica or silicon dioxide, SiO(2), which remains a solid even at blast furnace temperatures. However, the silicon dioxide must
