Iron ore sintering

Due to the depleting reserves of traditional high-grade iron ore, there have been considerable changes in iron ore resources available throughout the world, especially in steel mills in East Asia. Fig. 15.17 shows the change in iron ore sources used by the Japanese steel industries during the period from 1971 to 2007.

Mining

For iron ore this involves crushing the ore and then concentrating it in different ways, for example by milling, flotation or magnetic separation. At some sites the ore is processed further and pelletised for use in direct reduced iron (DRI) steelmaking. In the processing stage, the mined material is transformed into usable raw material.
