Blast furnace slag is waste discharged from blast furnace during pig iron smelting. It is mainly composed of gangue, ash, fluxing agent and other impurities that can not enter pig iron. Normally, each ton of pig iron smelting will produce about 0.25 tons to 1.2 tons of blast furnace slag, which has become a serious problem in the early industrial solid waste.

Blast Furnace Slag is formed when iron ore or iron pellets, coke and a flux (either limestone or dolomite) are melted together in a blast furnace. When the metallurgical smelting process is complete, the lime in the flux has been chemically combined with the aluminates and silicates of the ore and coke ash to form a non-metallic product called blast furnace slag.
Ore smelting. The water carries the slag in its slurry format to a large agitation tank, from where it is pumped along a piping system into a number of gravel based filter beds. The filter beds then retain the slag granules, while the water drains away and is returned to the system.
