: 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 accelerating energy consumption and increased GHG emissions for every tonne of iron ore

: Iron ore extraction techniques - ScienceDirect

2015-1-1 Iron ore was won by drilling and blasting ().As mining technology generally developed, so did drilling techniques and the explosives used. Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be self-supporting. However, he states that in later years where the mining had progressed to the dip, this ...
