Iron Ore Processing Techniques
Iron Ore
The estimated greenhouse gas emissions were 11.9 kg CO 2 e for mining and processing 1 tonne of iron ore. The embodied energy values were 153 MJ/t ore for iron ore. The results showed that loading and hauling made the largest contributions (approximately 50%) to the total greenhouse gas emissions from the mining and processing of iron ore.

Steel Production
The blast furnace uses coke, iron ore and limestone to produce pig iron. Coal traditionally has been a key part of the coke-making process. The coal is crushed and ground into a powder and then charged into an oven where it is heated to approximately 1800°F in the absence of oxygen. As the oven is heated, the coal begins to melt so most of the ...
