When the mining is done, the process must be reversed. Either the supports are gradually removed in 2- or 4-foot (0.6- or 1.2-meter) segments or the supports on one level are obliterated by drilling and blasting the ore on the level above it in a special pattern so that the supports on the level below fall in.

Processes and Procedures in the Extraction of Iron

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.

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.
