03/04/2014· Low grade iron ores cannot be used as such for the production of iron and steel and need to be upgraded to reduce its gangue content and increase its Fe content. The process adopted to upgrade the Fe content of iron ore is known as iron ore beneficiation (IOB).
EUROPA Energy Efficiency in the Iron and Steel Industry
The iron and steel industry is one of the largest industrial emitters of CO 2, accounting for between 4% and 7% of anthropogenic CO 2 emissions globally. In the past 40 years 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
Hematite Processing by Flotation
Direct shipping of high grade iron ore, because of depletion or partial depletion of reserves, or high costs of operation has forced operators to use some means of beneficiation to produce an acceptable product with the lower grade iron ore reserves. Deposits of comparatively lower grade iron ore that remain relatively untouched or by-passed, are now most important because of increase in
