Ironmaking 101 From Ore to Iron with Blast . 2017-10-10 Ironmaking Blast Furnace. Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities.

2017-10-10  Iron is made by reacting iron ore (iron oxide and impurities), coke (a reductant) and limestone (CaCO 3) in a blast furnace. Iron ores with lower iron content such as taconite are first processed to concentrate the iron level and drive off volatile impurities. The iron ore is dressed or crushed into 0.5-1 in. chunks, which increases surface area for reactions. Magnetic separation is used to remove some of the undesirable minerals or gangue in the crushed

MAXIMIZING LOW FE HYGROSCOPIC IRON ORE

The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.

In those cases where iron ore alumina is less than 1% the alumina content in the slag hardly goes above 10%. But in some iron ores (normally found in India) alumina content is 2% and higher (Raghukumar 2012).

Iron ore sinter /pellets are redirected from the wall of the blast furnace to the center using the bell-less top charging equipment. The top gas utilization (TGU) improves from 47.5 to 49.0% (an increase of 1.5%) due to better contact of the ferrous burden with the CO-rich gas in the furnace center.
