    Pure iron is a soft, grayish-white metal. although iron is a common element, pure iron is almost never found in nature. the only pure iron known to exist naturally comes from fallen meteorites. most iron is found in minerals formed by the combination of iron with other elements. iron oxides are the most common. those minerals near the surface of the earth that have the highest iron content are known as iron ores and are mined commercially.

  • The 6 steps to modern steel production explained metro

    Iron ore is converted into various types of iron through several processes. the most common process is the use of a blast furnace to produce pig iron which is about 92-94 iron and 3-5 carbon with smaller amounts of other elements. pig iron has only limited uses, and most of this iron goes on to a steel mill where it is converted into various steel alloys by further reducing the carbon content and adding other elements such as manganese and nickel to give the steel specific properties.

    Coal is a combustible black or brownish-black sedimentary rock occurring in layers or veins called coal beds or coal seams. coal is composed primarily of carbon, along with variable quantities of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. a fossil fuel, coal forms when dead plant matter is converted into peat, which in turn is converted into lignite, then sub-bituminous coal, bituminous coal, and lastly anthracite. this involves biological and geological processes that take place over time.

    The introduction of the steam pump by thomas savery in 1698 and the newcomen steam engine in 1712 facilitated the removal of water and enabled shafts to be made deeper so more coal could be extracted. a number of newcomen engines were successfully put to use in britain for draining hitherto unworkable deep mines, with the engine on the surface. these large machines, requiring a lot of capital to build, were extremely inefficient by modern standards, but greatly increased the scope of coal miningwhen located where coal was cheap at pit heads.
