Slag is a fused agglomerate, usually of silicates, which
separates during metal smelting and floats on the surface
of the molten metal. It is formed by the combination of
flux with gangue of ore, ash of fuel and perhaps furnace lining.
Slag is often used as the medium to separate
impurities from metal.
Slag also means the residue or ash from coal
gasification processes. It may run as high as 40%
depending on the rank of coal used.
