Calcination The concentrated ore is heated in supply of air on the shallow hearth of Reverberato

extraction of iron in a blast furnace reductionhaematite is added to the top of the furnace along with coke (i.e. carbon) and limestone. three reactions take place during this extraction. firstly, the carbon in the blast furnace burns with the hot air to form carbon dioxide. this reaction produces a lot of heat, and is the main source of heat in the furnace.extraction of iron extraction of iron from haematiteextraction of iron is based on the reduction of haematite (fe2o3) with carbon.. details of extraction. the process of the extraction of iron is carried out by the following steps concentration of ore. calcination or roasting of ore. reduction of ore. concentration of oreiron extraction and steelmaking chem not cheemaug 18, 2020· haematite is in turn hidden in rocks underground. therefore, to get h of iron, we need to first mine iron ores, chemically convert haematite into iron, and remove any impurity. the entire process is energy intensive and spews out loads of carbon dioxide. haematite is a mineral made of iron(iii) oxide, fe 2 o 3. it is mined for the extraction of iron.extraction of iron concentration of ore an overviewsep 23, 2019· hematite is concentrated by gravity separation process which is a method based on the difference in specific gravities of the metallic ore and gangue particles. the oxide being heavier settles to the bottom while lighter impurities come to the surface and are removed.
