Typically, iron ore contains a host of elements which are often unwanted in modern steel. Silicon. Silica (SiO 2) is almost always present in iron ore. Most of it is slagged off during the smelting process. At temperatures above 1,300 °C (2,370 °F) some will be reduced and form an alloy with the iron. The hotter the furnace, the more silicon ...
As-mined iron ore contains lumps of varying size, the biggest being more than 1 metre (40 inches) across and the smallest about 1 millimetre (0.04 inch). The blast furnace, however, requires lumps between 7 and 25 millimetres, so the ore must be crushed to reduce the maximum particle size.
