Energy Efficiency and CO Reduction in the Iron and Steel

there has been a 50% reduction in energy consumption in the industry in Europe. This has mainly been due to the increased use of recycled scrap iron, from a 20% share in the 1970’s to around 40% today, while the manufacture of iron from iron ore has declined. However, a complete shift to recy cling is limited by the availability and quality

CHAPTER 1 MINERAL DRESSING

The ore lumps from the mines have the lump size of 10 100 cm while the individual minerals have grain sizes below 0.1 mm. Hence, the first step in any ore dressing plant is to aim at liberation by size reduction or comminution. Comminution of any ore is carried out in several stages using different crushing equipments.
