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.
iron ore mining is classified into two categories- manual mining and mechanized mining methods. haematite and magnetite are the most commonly found iron ore minerals. deposits of iron ore such as haematite containing iron oxide are found in sedimentary rocks from which the oxygen is removed from the iron oxide in a blast furnace to give iron as a result.
(1) the above quote by walter van brunt (1922) really encapsulates the history of all of the four iron mining "ranges" of northern minnesota. where the life span of most mining districts lasts only years or tens of years, mining in the iron ranges of minnesota has spanned over 130 years and is still going strong.
slide 2 of 6. the mining of iron ore iron ore mining was a thriving industry in many parts of the world, with the smelters being located as close to the mines as possible. however as larger mines where more efficient mining of higher iron content ore became effective, the smaller mines fell by the wayside.
