Mining of Iron Ores IspatGuru

Mining techniques usually consist of two types based on excavation methods. These are surface mining and underground mining (sub surface mining). Iron ore is almost exclusively mined by surface operations. The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods.

Processes and Procedures in the Extraction of Iron

2021-1-13  The extraction of iron from its ores is quite a technical process. The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace. These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeres.

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

2018-3-9  Ore handling involves mucking out the blasted material at the front, transporting it on the sublevels, and dumping the ore into process. As compared to other mining methods, sublevel caving allows for a quicker and less expensive mining process. However, sublevel caving leads to greater dilution and is therefore used for lower ore bodies.
