The first iron mining techniques used charcoal which was mixed with iron ore in a bloomery. When heating the mixture and blowing air (oxygen) in through bellows, the iron ore is converted to the metal, iron. The chemical reaction between iron oxide and carbon is used here to produce iron metal. The balanced chemical equation for the reaction is:

Iron ore extraction techniques - ScienceDirect

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 ...

Coal and iron ore, for example, typically occur in shallow-dipping stratified deposits. Thus mining benches can be designed to be long and straight, facilitating the use of an overland conveyor and minimising expensive crusher repositions. Deep gold and copper applications, however, require a high vertical rate of mining that in turn require crusher repositioning to be more frequent.

Iron processing - Ores | Britannica

Iron processing - Iron processing - Ores: Iron ores occur in igneous, metamorphic (transformed), or sedimentary rocks in a variety of geologic environments. Most are sedimentary, but many have been changed by weathering, and so their precise origin is difficult to determine. The most widely distributed iron-bearing minerals are oxides, and iron ores consist mainly of hematite (Fe2O3), which is ...
