New Applications for Iron and Steelmaking Slag
New Applications for Iron and Steelmaking Slag –41– NKK TECHNICAL REVIEW No.87 (2002) Slag 4.2 Effect of absorbing CO2 Theoretically speaking, 1 mol of CO2(44 g) is absorbed by 1 mol of CaO (56 g) when solidifying steelmaking slag by carbonation. The main sources of CaO in the slag are calcium silicate compounds such as 2CaOSiO2and 3CaO SiO2.

Industrial uses of slag (the use and re-use of iron and steelmaking
Jul 18, 2013During ironmaking as well as during steelmaking, significant amounts of slag are produced. Two decades ago, more than 13 million tonne (mt) of blast furnace slag and 4 mt of steelmaking slag per annum were produced in the USA alone. It is therefore not surprising that many attempts have been made to re-use iron and steelmaking slags.
