The conventional wet granulation process produces a mixture of granular slag <5 mm and a lot of water. A more efficient modern granulation system uses high-pressure water jets that impinge on the stream of molten slag at a water-slag ratio of about 10 to 1 by mass. Another process, referred to as air granulation, involves the use of the pelletizer.

The term "slag" originally referred to slag produced by metal manufacturing processes, however it is now also used to describe slag that originates from molten waste material when trash and other .

Blast Furnace Slag | National Slag Association

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.

Steel manufacture

Steelmaking slag (BOF and EAF) is cooled similarly to aircooled BF slag and is used for most of the same purposes. As the production process varies at this stage depending on the type of steel being made, the resulting slags also have diverse chemical properties making them more difficult to use than ironmaking slags.
