Lump ore and agglomerates (namely pellets and sinter) are the feed materials for the blast furnace to produce pig iron, which is further refined with oxygen in the converter to produce liquid steel. Common iron ore contains Fe 2 O 3, Fe 3 O 4, and FeO, which have to be reduced with the help of reductants.

网页Crushed ore is divided into various fractions by passing it over sieves through which undersized material falls. In this way, lump or rubble ore (7 to 25 millimetres in size) is separated from the fines (less than 7 millimetres). If the lump ore is of the appropriate quality, it can be charged to the blast furnace without any further processing.

After the coarse ore has been extracted, it is crushed directly at the deposits with the aid of cone crushers or jaw crushers to more manageable sizes of approx. 15 mm. This is also known as lump ore. In addition to lump ore, fine ore (approx. 1 mm) and ground ore (ore powder) (approx. <0.1 mm) can also be obtained by crushing and grinding.
