Procedure For Mining Iron

How iron is made material manufacture making

Those minerals near the surface of the earth that have the highest iron content are known as iron ores and are mined commercially Iron ore is converted into various types of iron through several processes The most common process is the use of a blast furnace to produce pig iron which is about 92 94 iron and 3 5 carbon with smaller amounts

How is Iron Ore Mined PEDIAA

· 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
