Iron and steel slag, also known as ferrous slag, is produced by adding limestone (or dolomite), lime and silica sand to blast furnaces and steel furnaces to strip impurities from iron ore, scrap and other ferrous feed materials and to lower the heat requirements of the iron- and steelmaking processes.
The slag processor may also be required to satisfy moisture content criteria (e.g., limit the amount of moisture in the steel slag aggregate prior to shipment to a hot mix asphalt plant) and to adopt material handling (processing and stockpiling) practices similar to those used in the conventional aggregates industry to avoid potential segregation.

About 100 – 200 kg of BOF slag is generated per ton of liquid steel. This material is often used in projects like road construction, but this route provides little energy efficiency gains. Steel slag can also be used in the cement clinker manufacturing process. The result is an increase in clinker production of up to 15% with no net increase in CO2 emissions.
