however for iron to be of any use the impurities must be removed. This is done by a process involving a blast furnace. Extremely high temperature in the range of 870°C are reached within the blast furnace and this heat causes reactions to occur within the blast furnace that remove some of the impurities from the iron ore. The materials placed

The above reactions are highly simplified forms of complex interactions that actually happen inside a blast furnace. ThyssenKrupp said in its release, “In the classic blast furnace process, around 300 kilograms of coke and 200 kilograms of pulverised coal are needed to produce a tonne of pig iron.

Hudson Valley Iron-Ore Mining Industry: A History of

Aug 20, 2012 They built a bloomery, a furnace used for smelting iron ore. Workers would heat the mineral and beat out all excess material with a hammer, leaving only pure iron behind. They continued this process until 1751, when they constructed their first blast furnace, which heated the magnetite with limestone over a 2,000-degree charcoal fire.

Iron processing Iron making Britannica

Iron processing Iron processing Iron making: The primary objective of iron making is to release iron from chemical combination with oxygen, and, since the blast furnace is much the most efficient process, it receives the most attention here. Alternative methods known as direct reduction are used in over a score of countries, but less than 5 percent of iron is made this way.
