How Is Iron Extracted From the Earth? Reference
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 oreThe ore obtained after mining contains iron in the form of iron oxide pure iron is obtained, therefore, by the reduction of this ore This process is carried out in the blast furnace Temperature How is iron ore extracted from the ground AnswersExtracting iron from iron ore using a Blast Furnace The common ores of iron are both iron oxides, and these can be reduced to iron by heating them with carbon in the form of coke Coke is produced by heating coal in the absence of air Coke is cheap and provides both the reducing agent for the reaction and also the heat sourceThe Extraction of Iron Chemistry LibreTexts

What Are the Benefits of Mining? Research Summary
A typical mining operation Mining is the practice of extracting ore, coal, clays, soils, or minerals from the ground for the purpose of using them Mines have existed for thousands of years In ancient times mines consisted of short tunnels dug into the sides of hills or mountains where veins of metals, minerals, or coal had been discovered on The iron ore shown to the right was excavated from Skógar, a Vikingage ironmaking site in Iceland The larger piece is about 2cm (less than 1in) in the long dimension Sometime about 1000 years ago, someone gathered this iron ore, processed it, transported it to the iron smelting site, but for unknown reasons, never used it in a smeltHurstwic: Iron Production in the Viking AgeDec 11, 2012 Extracting iron from iron ore using a Blast Furnace a final ground slag which can be used in kitchen sinks, industrial equipment for food and drink processing: Extraction of iron To extract the iron from iron(lll) oxide, we remove the oxygen chemically oxidewhat equipment is used to extract iron from the ground
