  • What is the purpose of limestone in a blast furnace?

    limestone is used to remove impurities in the furnace and the main impurity of the blast furnace is silica (sand and rock) which is silicon dioxide silicon dioxide is a solid at furnace temperatures so it reacts with calcium oxide from the decomp.

  • Limestone, scaling, fouling in water

    Chemically limestone is mainly calcium carbonate (CaCO3): a mix of the calcium ion (Ca++) and the carbonate or carbone oxide (CO3--) Limestone is formed (scaling) when water containing particles of calcium carbonate evaporate, leaving behind the sediment deposit The water pressure compacts the sediment, creating limestone.

  • dissolution of limestone definition: The solubility of

    The solubility of calcite (and hence of limestone) in pure water is very low, but is vastly increased in the presence of carbon dioxide This gas, dissolved in the water to produce carbonic acid, permits dissociation of calcium carbonate, and dissolution rates and loads are therefore directly related to carbon dioxide content , This process.

  • PROCESS DESCRIPTION

    PROCESS DESCRIPTION In a limestone contactor, water flows through a bed of crushed sieved limestone in a similar way as it would flow through a sand filter (Spencer, 2000) The pH of water that flows through the limestone bed will be adjusted until it nears equilibrium with calcium carbonate (CaCO3(s)) The components of a contactor include a.
