Extracting iron from iron ore • Ekomuseum Bergslagen

The process of manufacturing iron advanced with the extraction of iron from the ore First, the ore was crushed into small pieces, which were then roasted toIron ore was won by drilling and blasting ()As mining technology generally developed, so did drilling techniques and the explosives used Smith (1990) reported that the Cleveland deposit was associated with a very strong stone roof rock (known as “dogger”) allowing mine drivages to be selfsupporting However, he states that in later years where the mining had progressed to the dip, thisIron ore extraction techniques ScienceDirect

Processes and Procedures in the Extraction of Iron

The extraction of iron from its ores is quite a technical process The iron ore is first roasted in air to produce iron(III) oxide which is mixed with coke and limestone and then further heated to a very high temperature in a blast furnace These materials are loaded into the blast furnace from the top while a blast of hot air is introduced into it from beneath via small pipes known as tuyeresThis concentrated ore is mixed with limestone (CaCO 3) and Coke and fed into the blast furnace from the top It is in the blast furnace that extraction of ironExtraction of Iron | Metallurgy | Blast Furnace and Reactions

The extraction of iron from its ore is a very long and forlorn process that separates the useful components from the waste materials such as slag What happens in the Blast Furnace? A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast ofFine ore and ore powder, on the other hand, are specially processed for the blast furnace process This ore processing will be discussed in more detail in the next section Iron ore processing After the iron ore has been prepared by crushing and grinding duringIron ore mining and dressing tecscience

Iron ore isn't pure iron oxide – it also contains an assortment of rocky material This wouldn't melt at the temperature of the furnace, and would eventually clog it up The limestone is added to convert this into slag which melts and runs to the bottom The heat of the furnace decomposes the limestone to give calcium oxideSteps of Extraction Step1: Concentration Step2: Calcination The ore is then heated in absence of air (calcined) This results in decomposition of carbonates into oxides and then ferrous oxide is converted into Ferric Oxide FeCO 3 FeO CO 2 4Extraction Of Iron SlideShare
