Method of Mining Iron Ore. Iron Ore is mined by a method called open cast method. The process is as follows: Explosives are used to remove the overburden rocks. A powerful machine called a dragline is then used to pile the iron ore into a heap. A monitor is then used to direct a powerful jet of water towards the heap.

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.

The Step-by-Step Process of Producing Iron from Iron Ore. Some 3000-4000 years ago, the ancient Egyptians derived iron from the fallen meteorites (or so they say), carved them and made tools and equipment besides jewelry. We have come a long way since then. Now, first of all, pure iron is rarely available (except if one or two meteorites crash).

Compared to other mining methods, room-and-pillar mining is a low-cost method with a low recovery rate (since some ore is left behind in pillars). Yet, the method causes very little dilution as the contact between ore and waste is limited due to the waste being on top and ore being at the bottom. Direct operating costs for room-and-pillar method range from $5-$20/tonne.
