How is Iron Ore Mined Pediaa.Com

Nov 21, 2014· Open pit mining is used for the production of iron ore. Iron ore can be mined from all places in the world but to be commercially viable, the percentage of iron in this iron ore needs to be at least 20%. This is because lower iron content in the ore will render all the money and effort exerted in mining the ore from under the surface of the

How Is Iron Extracted From the Earth? Reference

Mar 26, 2020· Iron ores in the form of hematite (ferrous oxide) and magnetite are removed from the earth through mining. The use of heavy mining equipment is necessary to dig out large pits in an area with a large deposit of iron ore; however, because iron does not occur naturally, it is necessary to use a blast furnace to separate or refine iron from the other substances in the iron ore.

What are the main methods of mining? American

There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, beach sands, or other environments.
