Product description:

The blast furnace is where the iron is extracted from the iron ore. Solid ore and coke are fed into the furnace from the top, while a stream of very hot air (1,200° C) from the bottom causes the combustion of the coke, with its virtually pure carbon content. This produces carbon oxide, which "reduces" the iron oxide by removing oxygen, separating the iron. The heat created by the combustion melts the iron and gangue (aggregates of minerals in an ore) into a liquid. The gangue, being lighter, floats to the surface of the molten iron, known as "pig iron". Slag, which is the residue created by the molten gangue, can be used in other industrial applications, like road construction or cement production.
