Iron ore a type of coal called coke which contains 85 carbon and lime are added to the top of the blast furnace Hot air provides the oxygen for the reaction The temperature of a blast furnace can be up to 1200C The reaction takes place inside the furnace and molten iron is removed from the bottom Jun 21 2018 Direct reduced iron DRI process In addition to the process route via the blast furnace process there is another option for extracting crude steel from iron ores using the socalled direct reduced iron DRI process secondary routeThe starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure Considering flotation as the most suitable technology for the treatment of such type of material future research should focus on a deep fundamental study of the collectordepressant mechanism interaction with the ironbearing and gangue minerals especially in those ores with a high amount of aluminacontaining minerals

Jan 24 2020 Iron ore is an essential component for the global iron and steel industries Almost 98 of mined iron ore is used in steel making About 50 countries mine iron ore with Australia and Brazil Apr 28 2016 1 Campaigning For metallurgical reasons if there are some ore types that can cause process difficulties if mixed with other ores The problematic ore might be stockpiled until sufficient inventory allows one to process that ore ie campaign through the mill Such stockpiles will only grow as large as the operator allows them to grow Sintered iron ore and coke are layered inside a 100 m long furnace then hot air at 1200 degree Celsius is blown into the blast furnace from the bottom causing the coal to burn and this heat in turn burns the iron ore to create molten iron at a temperature of 1500 degree Celsius This is also called hot metal pig iron in the industry
