Ironmaking 101 From Ore to Iron with Blast Furnaces
Oct 10, 2017 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 ...
THE BLAST FURNACE IRON PRODUCTION
Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.

Direct reduced iron process tecscience
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 so-called direct reduced iron DRI process secondary route.The starting point for the efforts to find an alternative to the blast furnace process was the relatively high process expenditure.

in a huge container called a blast furnace. Iron ores such as haematite contain ironIII oxide, Fe 2 O 3. The oxygen must be removed from the ironIII oxide in order to leave the iron behind.
1123 Taconite Ore Processing
Processing of taconite consists of crushing and grinding the ore to liberate iron-bearing particles, concentrating the ore by separating the particles from the waste material gangue, and pelletizing the iron ore concentrate. A simplified flow diagram of these processing steps is shown in Figure 11.23-1.
