every construction of man contains at least a little iron. it is also one of the est metals and was first fashioned into useful and ornamental objects at least 3,500 s ago. pure iron is a soft, grayishwhite 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 w see full list on madehow historians believe that the egyptians were the first people to work with small amounts of iron, some five or six thousand s ago. the metal they used was apparently extracted from meteorites. evidence of what is believed to be the first example of iron mining and smelting points to the ancient hittite culture in what is now turkey. because iron was a far superior material for the manufacture of weapons and tools than any other known metal, its production was a closely guarded secret. howev see full list on madehow 1. 1 after processing, the ore is blended with other ore and goes to the blast furnace. a blast furnace is a towershaped structure, made of steel, and lined with refractory, or heatresistant bricks. the mixture of raw material, or charge, enters at the top of the blast furnace. at the bottom of the furnace, very hot air is blown, or blasted, in through nozzles called tuye#39;res. the coke burns in the presence of the hot air. the oxygen in the air reacts with the carbon in the coke to form ca see full list on madehow the blast furnace operation is highly instrumented and is monitored continuously. times and temperatures are checked and recorded. the chemical content of the iron ores received from the various mines are checked, and the ore is blended with other iron ore to achieve the desired charge. samples are taken from each pour and checked for chemical content and mechanical properties such as strength and hardness. see full list on madehow there are a great many possible environmental effects from the iron industry. the first and most obvious is the process of open pit mining. huge tracts of land are stripped to bare rock. today, depleted mining sites are commonly used as landfills, then covered over and landscaped. some of these landfills themselves become environmental problems, since in the recent past, some were used for the disposal of highly toxic substances which leached into soil and water. the process of extracting iro see full list on madehow on the surface, the future of iron productionespecially in the united statesappears troubled. reserves of highquality ore have become considerably depleted in areas where it can be economically extracted. many longtime steel mills have closed. however, these appearances are deceiving. new
