Get PriceIron Extraction The common ores of iron are its oxide hematite Fe 2 O 3 and magnetite Fe 3 O 4 They can be reduced to iron by heating them with carbon in the form of coke The coke burns in an exothermic reaction At the high temperatures the carbon dioxide reacts with more coke to make carbon monoxide
Get PriceAt the bottom of the furnace the iron ore is chemically reduced The blast reacts with the coke; carbon dioxide and carbon monoxide are formed at temperatures of up to 2024 °C The carbon monoxide removes the oxygen from the iron ore resulting in pig iron production Slag is formed from the other ore components and the additions
Get PriceDirect reduction in which iron ores are reduced at temperatures below the metal s melting point had its origin in such experiments as the Wiberg Soderfors process introduced in Sweden in 1952 and the HyL process introduced in Mexico in 1957 Few of these techniques survived and those that did were extensively modified
Get PriceThe inhibitor of iron ore uses the sodium silicate tannin and sodium lignosulfonate and their inhibitory effect is the best when the pH value is 8 9 In terms of the ore properties of hematite ore the reverse flotation method is more advantageous as the method used for the extraction of iron from hematite than the positive flotation method
Get PriceIron when extracted from iron ore such as haematite containing iron III oxide Fe2O3 in a blast furnace is called iron extraction blast furnace metallurgy In this reduction reaction oxygen is removed from the iron III oxide to leave behind iron Generally the extraction of metals and their isolation are based on three major procedures
Get PriceMagnetite and hematite are iron oxides; however the extraction of iron from an iron oxide involves a series of steps that begins when mined iron ore is crushed into smaller pieces by a crusher and then washed The second step in the process is calcination or roasting of the ore which removes certain impurities carbon dioxide and other
Get PriceTherefore the solid sponge iron begins to carburize at a lower temperature 400 ℃～ 600 ℃ The chemical reaction is as follows 2CO 3Fe → Fe3C CO2 or 3Fe liquid C solid → Fe3C Slagging process Slagging is a process in which gangue in ore and ash in fuel are combined with flux and removed from blast furnace
