In contrast to most substances, you can also magnetize iron, making it useful in the creation of electric motors and generators. Finally, there certainly aren't any iron shortages to worry about. The Earth's crust is 5 percent iron, and in some areas, the element concentrates in ores that contain as much as 70 percent iron.
Iron ore are the rocks or minerals by which metallic iron is derived. Iron ores that carry a high quantity of hermatite or magnetite can be fed directly into blast furnaces in the iron production industry. The business of mining iron ore is a high volume, low margin industry because of the low value of iron.
Mining helps industries to grow by providing raw materials to industries; Many industries obtain their raw materials from the mining sector. For example, building and construction industries get some of their raw materials from processed asbestos and iron ore. Heavy engineering firms obtain iron and steel from the Zimbabwe Iron and Steel Company.

Mining, process of extracting useful minerals from the surface of the Earth, including the seas. A mineral, with a few exceptions, is an inorganic substance occurring in nature that has a definite chemical composition and distinctive physical properties or molecular structure. (One organic
Exploitation of existing iron ore deposit is the easier part of the mining operations. The harder part is to find new ore deposits and to define their extent and the iron content (grade). Exploration is the process by which the accumulations of iron ore minerals can be found in the earth's crust.
Likewise, mining engineering is a field with a long history. Archaeological studies have revealed that mining played an important role in prehistoric times, as evidenced by the flint mines in the countries we today call England and France. The Romans were renowned for their innovations in mining engineering.

Everyday, in nearly every facet of life, we use products created by Minnesota's iron mining industry. Unearthed on northeastern Minnesota's Iron Range in 1884, iron mining has long-played, and continues to play, a vital role in every individual's life.
World mine production of iron ore, by country, 2018 (p) Natural Resources Canada; U.S. Geological Survey; An adjustment in the U.S. Geological Survey's methodology to estimate usable ore production instead of crude ore production resulted in adjusted totals from China beginning in 2015 and in lower overall world mine production.
Increasing iron ore demand, coupled with the depletion of high-grade hematite ores in the United States, after World War II led to development of lower-grade iron ore sources, principally the utilization of magnetite and taconite. Iron-ore mining methods vary by the type of ore being mined.
Minnesota's iron mining industry not only has significant economic impact in the areas in which the iron is mined. The effects of Minnesota's iron mining industry can be felt far and wide – on local, regional, national and even international levels.
