Slag: From By-product to Valuable Construction Material. By Stephen Dietz 07.29.2014. Slag is a by-product of the metallurgical smelting process. Slag has a double role: it permits removal of impurities, known as gangue, from the melt by forming oxides. It also allows exchange reactions with the liquid metal, permitting control of the process ...

Iron and steel scrap is a vital raw material for the production of new steel and cast-iron products. The steelmaking and foundry industries in the United States are highly dependent upon the ready availability of scrap from manufacturing operations and from the recovery of products that are no longer used or needed. The steel industry has been recycling steel scrap for

Iron and steel slags are coproducts of iron and steel manufacturing. In the production of iron, the blast furnace is charged with iron ore, fluxing agents, usually limestone and dolomite, and coke as fuel and the reducing agent. The iron ore is a mixture of iron oxides, silica, and alumina. From this and the added fluxing agents molten slag and ...

Steel and steel slag annual output in 2010 in China reached to 626.7 million tons and 90 million tons respectively (Ren et al., 2012). The amount of deposited steel slag (mainly BOFS) in China has been estimated to more than 300 million tons, which leads to the occupation of farm land and pollution of groundwater and soil (Yi et al., 2012).

The steel industry is finding ways and means to utilize the steel slag in other applications like construction & road making, soil conditioning, rail ballast. However there are problems and issues. The steel slag need to be properly aged and ground to very fine size before it can be explored to be utilised, which incur substantial cost.
