Environmental impact of iron ore mining - Wikipedia
Mining and processing. Most iron ore is produced from open-pit mines. After the iron ore is out of the ground, it may be shipped to the iron and steel manufacturing plant. If the ore contains less than 60 percent iron, it is usually beneficiated to an iron-ore concentrate typically containing greater than 60 percent iron.

Analysis of life-cycle GHG emissions for iron ore mining ...
Iron content (ore grade) varies from 15% to 60% and is the largest contributor (40%) to the uncertainty of the results. Iron ore demand growth and the depletion of rich ore deposits will result in increased exploitation of lower grade ores with the concomitant increase in energy consumption and GHG emissions.
