Iron ore extraction techniques - ScienceDirect

2015-1-1  Iron ore was won by drilling and blasting . As mining 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

Direct Biohydrometallurgical Extraction of Iron from Ore

hydrometallurgical extraction of iron. The problems in iron extraction by this means have been: 1. The standard leaching method is dissolution of fully-oxidized ore by acid. However, iron oxidized to the Fe +3 (ferric) state requires a very acidic solution to dissolve, and this results in very high acid consumption. 2.

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.
