2021-10-31  Extracting iron from iron ore. In the 12th century, men started to mine iron ore from rock. They learnt how to recognize rock that contained iron ore and broke off pieces of rock by lighting fires against it, to make it brittle. The work was done from the surface down, excavating the rock in opencast mines and following the veins of ore.

Direct Biohydrometallurgical Extraction of Iron from Ore ...

2005-10-1  A completely novel approach to iron extraction was investigated, based on reductive leaching of iron by anaerobic bacteria. Microorganisms were collected from an anaerobic bog where natural seepage of dissolved iron was observed. This mixed culture was used to reduce insoluble iron in a magnetite ore to the soluble ferrous (Fe {sup +2}) state.

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 ...
