Processes and Procedures in the Extraction of Iron ...

2021-5-2  The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

Analysis of life-cycle GHG emissions for iron ore

2018-10-1  As the iron ore grade declines, the rate of increase in GHG emissions from mining accelerates. For example, when iron ore grade decreases from 40% to 35%, the average GHG emissions for mining increases by 12 kg CO 2 e/tonne. In contrast, the same 5% iron ore grade decrease from 20% to 15% would lead to 52 kg CO 2 e/tonne. Thus, China will face ...
