    Blast furnace - Wikipedia

    A blast furnace is a type of metallurgical furnace used for smelting to produce industrial metals, generally pig iron, but also others such as lead or copper. Blast refers to the combustion air being "forced" or supplied above atmospheric pressure.. In a blast furnace, fuel (), ores, and flux are continuously supplied through the top of the furnace, while a hot blast of air (sometimes with ...

    Slag - Wikipedia

    In nature, iron, copper, lead, nickel and other metals are found in impure states called ores, often oxidized and mixed in with silicates of other metals. During smelting, when the ore is exposed to high temperatures, these impurities are separated from the molten metal and can be removed. Slag is the collection of compounds that are removed.

    In the iron melters, iron slag is formed by fusion of limestone, ash and other fluxes added to the original ironsand (silica, aluminium, titanium). Iron slag is less dense than the molten iron in the large melters and so floats on top of the iron. This allows the slag to be tapped (poured) from the melter separately.
