Iron Ore - an overview ScienceDirect Topics

Because the raw materials are carefully controlled to produce consistent crude iron, the range of slag chemical composition is fairly narrow for a specific ore and furnace operation. The hot air blast to the furnace burns the coke and maintains the very high temperatures that are needed to reduce the ore to iron.

The Making of Iron Steel

2020-8-3  2.1 Iron Ore Composition Iron very rarely occurs in the earth's surface as a metal. It is widely distributed, combined with oxygen as iron oxides. In fact it is believed that iron makes up about 5% by weight of the earth's crust. Geologists recognise various types of iron ore, classified chiefly according to iron (Fe) content (see Table 1 below).
