ongoing costs associated in iron ore processing

Chapter 73. Iron and Steel

The amount of energy consumed in steel production varies widely with the processes used and the mix of scrap metal and iron ore in the feed material. The energy intensity of United States scrap-based plants in 1988 averaged 21.1 gigajoules per tonne while the Japanese plants consumed about 25% less. A model International Iron and Steel Institute (IISI) scrap-based plant required only 10.1 ...
