Iron is concentrated by the process of calcinations Once it is concentrated, the water and other volatile impurities such as sulfur and carbonates are removed This concentrated ore is then 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 iron occurs The extraction of Iron Ore Mining Techniques Metal Extraction
Extraction of Iron: Meaning, Purification, Extraction
27/09/2021 Extraction of Iron from its Concentrated Ore This concentrated ore is then mixed with limestone and coke which is fed into a blast furnace The extraction of ore occurs in the blast furnace as follows: Blast refers to the combustion air being supplied above the atmospheric pressure The blast furnace reduces the concentrated ore to its liquid chemical state A blast Mining and processing of iron ore involves coarse crushing and screening Iron ore is beneficiated by crushing and then separating the iron from the gangue minerals through screening This is usually so efficient that lower grade ore can be treated especially when the magnetite is quite coarseProcess Flow Diagram Of Iron Ore Mining And Benifeciation 12/01/2017 The crushed ore is brought from the hoppers to the jigs by chutes provided with gates at the lower end, just above the screen plates The screens are first covered closely with pieces of heavy ore about the size of hickorynuts; the crushed ore is then spread over this until it is level with the collar of the spider, about 2½ to 3 inches deep The springpole is connected Magnetite Processing Extraction Jig
