  • 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 selfsupporting However, he states that in later years where the mining had progressed to the dip, thisMining and processing of iron ore involves coarse crushing and screening Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarse Common iron ore crushers are jaw crusher, cone crusher and fine jaw crusherIron ore mining process and iron ore mining equipments Steel is made from iron ore, a compound of iron, oxygen and other minerals that occurs in nature The raw materials for steelmaking are mined and then transformed into steel using two different processes: the blast furnace/basic oxygen furnace route, and the electric arc furnace route Both processes are being continually improved to meet the challenge of lowemission steelmakingMaking steel | ArcelorMittal
