Mining of Iron Ores – IspatGuru

14/03/2014· The most predominant surface mining methods used for mining of iron ores are open pit mining methods and open cut mining methods. However a few underground iron ore mines are also in operation around the globe. The decision for employing surface mining or underground mining is dependent on the proximity of the ore body to the surface. Open pit

A Underground Method of Mining Iron Ore

Some ore deposits found in jasper-slates and in the horizon between these and their associated clay-slates; in the latter they are true contact-deposits. They are found in this jasper- and clay-slate formation under varied conditions, yet, in all, certain characteristic laws are preserved. The angle of dip varies from 15° to 20°, and up to 85° and even 90°, with the horizon.

Iron Ore in South Africa mining-jobs-south-africa

Iron Ore are rocks and minerals from which metallic iron can be frugally extracted. The ores are generally rich in iron oxides and differ in colour from dark grey, bright yellow, deep purple, to rusty red. Iron ore itself is usually found in the form of magnetite, hematite, goethite, limonite or siderite Hematite is also known as natural ore.

Iron ore extraction techniques ScienceDirect

Open pit mining of iron ore is fundamentally simple when compared to underground mining. While ore grades have to be maintained at high levels in order to satisfy the market, commercial advantage is gained by the application of high-capacity modern mining equipment, but volumes have to be high and costs so low to remain competitive.

Mining LKAB

LKAB places great emphasis on refining every element of the underground mining process, in order to make it as efficient as possible. From the Kiruna mine alone, more than 75,000 tonnes of iron ore are mined per day, which is roughly equivalent to the volume of a 12-storey building. You can read more about underground mining here.
