The primary use of iron ore is in the production of iron. Most of the iron produced is then used to make steel. Steel is used to make automobiles, locomotives, ships, beams used in buildings, furniture, paper clips, tools, reinforcing rods for concrete, bicycles, and thousands of other items.early all of Earth's major iron ore deposits are in rocks that formed over 1.8 billion years ago. At that time Earth's oceans contained abundant dissolved iron and almost no dissolved oxygen. The iron ore deposits began forming when the first organisms capable of photosynthesis began releasing oxygen into the waters.
Iron Iron is a trace mineral needed to make hemoglobin, the protein needed to carry oxygen throughout the body. Hemoglobin gives red blood cells their color, and stores most of the body s iron supply.Iron is also stored in muscle tissue, and helps supply the muscles with the oxygen needed to make them contract.Although iron is a trace mineral, it is extremely important, because a deficiency in this nutrient leads to a shortage of red blood cells, a condition known as anemia.Anemic individuals do not have an adequate supply of oxygen in their body, which leaves them tired, pale, and short of breath.ron is also stored in muscle tissue, and helps supply the muscles with the oxygen needed to make them contract.
