Iron Mining Process - Minnesota Iron

The rock is mixed with water and ground in rotating mills until it is as fine as powder. Separation The iron ore is separated from the taconite using magnetism. The remaining rock is waste material and is dumped into tailings basins. The taconite powder with the iron in it is called concentrate. Pellets

Iron ore extraction techniques - ScienceDirect

Jan 01, 2015  Iron ore was won by drilling and blasting ( Figure 7.1 ). 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.

Iron ore - Wikipedia

Iron ore mining methods vary by the type of ore being mined. There are four main types of iron ore deposits worked currently, depending on the mineralogy and geology of the ore deposits. These are magnetite, titanomagnetite, massive hematite and pisolitic ironstone deposits. Banded iron formations Main article: Banded iron formation

Mining - LKAB

Ore is extracted from LKAB's underground mines by means of sub-level caving. This mining method is based on creating cavities in the orebody through drilling and blasting, and allowing the ore to fall down to underlying levels by means of gravity, from where it is transported onwards by train or loader.

Mining - LKAB

The method is based on mining the ore in descending levels through drilling and blasting. The thickness of the slabs, known as the bench height, is 15 metres, and the slabs are worked downwards. Bench mining is an effective and well established mining method, which allows maximum extraction from the rock with a high degree of safety.
