 · 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 .

 · An average analysis of franklinite shows it to contain iron, %, manganese, %, zinc, %, oxygen, %. It is used as an ore of zinc, and the residue as an iron ore; its value is not quoted on the market. Crystals, in the cubic system, octahedrons, like those of magnetite. Found with other zinc ores. Hematite: Fe2O3

Extraction of iron Very unreactive metals are found directly in the ground as elements, eg. gold. Most metals are found in ores where they have reacted with other elements. Ores are rocks containing enough metal to make it economical to extract. We can extract the iron by reacting the iron oxide with a more reactive element.

Figure 4: A Blast Furnace for Converting Iron Oxides to Iron Metal. (a) The furnace is charged with alternating layers of iron ore (largely Fe2O3) and a mixture of coke (C) and limestone (CaCO3). (b) This blast furnace in Magnitogorsk, Russia, was the largest in the world when it was built in 1931.

 · Humans use iron in hemoglobin molecules in blood to allow for the transport of oxygen to tissues throughout the body. Although iron is an essential mineral, much of it is extremely toxic. Free iron in the blood reacts with peroxides to form free radicals that damage DNA, protein, lipids and other cellular components, leading to illness and sometimes death.

Uses of Cast Iron – Appliion Gray cast iron have also an excellent damping capacity, which is given by the graphite because it absorbs the energy and converts it into heat. A large damping capacity is desirable for materials used in structures where unwanted vibrations are induced during operation such as machine tool bases or crankshafts.

 · It disables the smelting recipes for iron ores, to make you have to build a refiner. Then, once you have a refiner, you can make refined iron ore which you can use in furnaces to make iron ingots. You can also use it with other mods, as .

 · Ores are naturally occurring rocks that contain metal or metal compounds in sufficient amounts to make it worthwhile extracting them. For example, iron ore is used to make iron and steel. Here, we providing a List of some Important metals and their ores. it is mainly useful for your upcoming competitive exams like SSC, UPSC etc.

3. After the scrap is melted, a variety of other ingredients are added. Some iron ore may be used to remove carbon, or carbon may be added if the carbon content is low. Limestone is added as a fluxing agent. Alloying elements are added at the very end of the operation. Oxygen gas is sometimes fired into the melt to speed up the heat.

Limonite in a ore of iron and is used as a pigment in the manufacture of paints. Besides for a few aesthetic lustrous botryoidal forms of Limonite, as well as the interesting pseudomorphs, Limonite is not of much interest to collectors.
